In this week's questions and answers show, I explain how Starship will enable enormous space telescopes, if James Webb can look at Hubble, and if future astronomers will have any way of learning about the expansion of the Universe and the Big Bang.
00:00 Start
01:46 Could Starship be a telescope?
04:26 Can JWST see Hubble?
06:10 Will elliptical galaxies restart star formation?
08:00 Will future civilizations know about the Big Bang?
11:38 How will the Lunar Gateway change robotic space exploration?
14:34 Where are the flagship missions?
15:50 How does artificial gravity work in space?
16:55 How many useful gravitational lenses are there out there?
19:11 What lies beyond space?
20:10 Will we definitively prove life beyond Earth?
23:57 Could you use the Moon as a gravitational lens?
24:40 Can we look back in time somehow?
26:10 Are there good careers in astronomy?
29:19 Could we learn anything getting close to black holes?
Want to be part of the questions show? Ask a short question on any video on my channel. I gather a bunch up each week and answer them here.

843: How JWST Sees in Color, Where Is Dark Matter, Did Earth Life Come from Space | Q&A 187
In this week's questions and answers show, I explain how JWST and other telescopes see color, how images from observatories are released to the public, and how much of the sky can JWST see. Also, a bunch of non-Webb questions too.
00:00 Start
01:55 [Tatooine] How does JWST see color?
09:58 [Coruscant] How are astronomical images released to the public?
12:52 [Hoth] How does JWST handle spacedust?
14:48 [Naboo] How is JWST pointed?
16:39 [Kamino] Could dark matter be detected in specific parts of the Universe?
18:52 [Bespin] Is dark matter just a smart guess?
23:10 [Mustafar] Why does Earth have water and the Moon doesn't?
26:09 [Alderaan] Is Panspermia inevitable?
28:28 [Dagobah] Is the Big Bang a past event or is it still happening?
29:43 [Yavin] What's the best telescope to see planets?
31:19 [Mandalore] If we mapped the CMB from Andromeda, would it look different?
33:10 [Geonosis] Why do we see light from long ago, shouldn't it have passed us?
34:49 [Corellia] How can we promote diversity in STEM?

842: Liquid Mirror Telescope with Dr. Paul Hickson
Dr. Paul Hickson is a professor of astronomy and astrophysics at the University of British Columbia. Dr. Hickson is overseeing a team that built a telescope out of liquid mercury in India. The International Liquid Mirror Telescope is 4 meters across and built on top of a 3,000-meter mountain in India. This will prove the technology and allow for larger and larger liquid mirror telescopes on Earth (and eventually in space).

In this week's Questions and Answers show, I answer what it would take to build a telescope as big as the Earth's orbit around the Sun, why SgrA* seems to have been rolled over on its side, and how we know the age of stars.
00:00 Start
01:50 [Tatooine] Could we have a telescope the size of Earth's orbit?
08:11 [Coruscant] Why is SgrA* rolled over on its side?
09:53 [Hoth] How do we know the age of stars?
14:19 [Naboo] Could you have a collection of smaller mirrors working together?
17:19 [Kamino] Why not build two Uranus missions?
19:11 [Bespin] Why do white dwarfs explode at 1.4 times the mass of the Sun?
21:23 [Mustafar] Where are the Voyagers?
22:20 [Alderaan] Could a meteor storm destroy satellites?
23:49 [Dagobah] Could aliens know there's life on Earth?
27:03 [Yavin] Has anyone ever built artificial gravity in space?
31:36 [Mandalore] How do we get more people to try stargazing?
33:06 [Geonosis] How do you orbit a Lagrange point?
35:31 [Corellia] Are there any missions to return to Pluto?

837: Cosmology and Relativity with Dr. Leah Jenks
Einstein's Theory of General Relativity has been tried and tested many times, and so far, Einstein was right. But we know his theory must be incomplete, as it still doesn't integrate with quantum mechanics. Where are physicists searching next for the future of cosmology and relativity? Dr. Leah Jenks is a PhD recipient from Brown University, and will become a KICP Fellow at the University of Chicago.

832: Jumping to Multicellular Life with Dr. William Ratcliff
How did life go from single-celled to multi-celled? Dr. William Ratcliff is an Associate Professor and Co-Director of the Interdisciplinary Ph.D. in Quantitative Biosciences at the School of Biological Science at Georgia Tech. Dr. Ratcliff and his collaborators are working with single cells of yeast, watching them make the jump to become multi-cellular organisms. It turns out, life has done this many times in the past, and not just the jump that created the modern animals we know of today.

07:16 [Hoth] Were dinosaurs hurled to space during an asteroid impact?
09:57 [Naboo] How do stars get bigger than red dwarfs?
12:36 [Kamino] Will there be new physics beyond Newton and Einstein?
15:43 [Bespin] What would happen if a small black hole passed through the Earth?
17:27 [Mustafar] Has water been found on the Moon?
20:13 [Alderaan] How bad is the dust on Mars?
21:54 [Dagobah] Where does a planet go if it's absorbed by a black hole and then radiated away?
24:11 [Yavin] Are telescopes generating too much data?
27:01 [Mandalore] Who will take over after us?
28:19 [Geonosis] What will be the next space propulsion systems?

816: Collecting Micrometeorites with Scott Peterson
Every day about 100 tonnes of space dust strikes the Earth's atmosphere. Most of these space rocks vaporize, but some fall to the Earth at meteorites. Did you know that there are particles from space falling on the roof of your house? My guest today is Scott Peterson. Scott collects micrometeorites from his house and takes pictures of them using a microscope. We'll talk about how to find them, identify them and photograph them for yourself.

19:38 [Bespin] Would I go to space?
21:43 [Mustafar] Could a telescope see features on an exoplanet?
23:57 [Alderaan] Can we see cosmic rays hitting our retinas?
25:26 [Dagobah] How can Parker Solar Probe fly so close to the Sun?
27:10 [Yarvin] Does the density of the Universe matter to advanced civilizations?
30:34 [Mandalore] Am I worried about solar flares?
32:31 [Geonosis] What if we put Hubble out to the orbit of Neptune?
34:46 [Corellia] What are some good targets for astrophotography?

813: Weird Orbits and How They Work with Dr. Renu Malhotra
My guest today is Dr. Renu Malhotra, a planetary scientist who specializes in planetary migration and orbital mechanics. Dr. Malhotra and her team have discovered that Pluto's orbit is surprisingly chaotic at small timescales and yet surprisingly stable at larger timescale. We'll talk about her research and the science of orbital mechanics that led to the current orbits of the planets in the Solar System.

805: W Boson Breaking the Standard Model with Dr. Paul Sutter
Particle physicists have announced an exciting discovery about the W Boson particle that challenges the Standard Model of Physics. To help me understand what was discovered and what it means for physics, I've invited Dr. Paul Sutter back to explain it. Paul is a fantastic science communicator and has a PhD in particle physics. The perfect person to help us make sense of this.

803: ILLEGAL Moon Residents, Space Power Plants, Center of the Universe | Q&A 179
In this week's questions show, I explain how other planets can have geostationary orbits, if sending tardigrades to the Moon is a violation of the Outerspace Treaty, and why everything orbiting the Sun is in perfect balance.
Here's a link to our Discord server: https://discord.gg/3nk8kAARUm
00:00 Start
00:53 Does Venus have a geostationary orbit?
02:34 Is sending tardigrades to the Moon violate the Outerspace Treaty?
06:30 Why is everything in stable orbit around the Sun?
08:50 Is there a telescope on the ISS?
10:33 How does the solar maximum work?
13:05 Does space solar power make sense?
15:40 Do rockets have to go into orbit around the Earth first?
17:15 When will a microscope go to Mars?
19:57 Could gravitational lensing let us see beyond the observable Universe?
21:53 Where will we see the surface of other worlds?
24:19 Could you go faster to blue shift light?
26:47 Do nuclear rockets need fuel?
28:03 Does time travel slower at the centre of the Universe?
29:49 Can black holes go supernova?

Episode 797: Fusion Rockets, Ditching Heat Shields, Looking Beyond the Edge of the Universe | Q&A 176
In this week's live Questions and Answers show, I explain how a more powerful rocket could reduce the need of a heat shield, if we could detect objects beyond the edge of the observable Universe through their gravity, and what are the largest objects (or spacecraft) that could hang out at a Lagrange Point?
00:00 Start
00:13 Why do we even need heat shields?
03:12 Could we detect objects beyond the observable Universe through their gravity?
05:42 Can massive objects last at Lagrange Points?
08:03 Will fusion drives enable interstellar travel?

13:11 Why do we assume dark energy is accelerating the expansion of the Universe?
17:08 Can Webb look in all directions?
19:01 Could we detect the Earth from 100 light-years away? What about our satellites?
22:24 Is everything still trapped inside the Big Bang?
24:34 How can people support Universe Today?
27:06 Are black holes really dark stars?
28:10 Would geothermal work on Mars?
30:53 How can Webb orbit L2 if nothing's there?
34:24 Can smaller black holes eat bigger black holes?
35:25 When will we stop wanting to colonize Mars?
36:48 Can dark matter be explained by black holes?

Episode 774: Q&A 164: Could Too Much Gravity Prevent a Civilization Going to Space? And More...
In this week's live questions and answers show, I speculate what kind of civilization could be permanently stuck on the surface of their planet, if rival nations could shoot down each other's spacecraft, and how do I really feel about the Space Launch System?
00:00 Start
01:01 How much gravity makes spaceflight impossible?
04:40 Could a rival shoot down a rocket during launch?
07:07 Should I apologize for advocating for SLS?
11:50 Do photons experience time?
13:42 Can you see Earth's lights from the Moon?
15:28 Can we detect exoplanets with their magnetic fields?
17:27 What missions do I wish were never cut?
20:21 Does finding life mean we're doomed?
22:45 Are galaxies orbiting something bigger?
23:42 Can a star collapse directly into a black hole?
25:36 Should we move away from complex telescopes?

Episode 764: Habitable Hycean Worlds: An interview with Dr. Nikku Madhusudhan
My guest today is Dr. Nikku Madhusudhan, a PhD astronomer at the University of Cambridge. Dr. Madhusudhan is one of the researchers who investigated the habitability of "hycean worlds"; ocean worlds with a thick hydrogen ocean. These worlds are completely alien to anything we have in the Solar System, and yet, could have a much wider region that remains habitable than terrestrial planets.

Episode 756: Q&A 154: How Big are Meteors? And More...
The new season has begun! We're back with an all-new series of question shows. In this week's episode, I provide a quick guide to seeing fireballs (bolides), which are the brightest meteors you can see (and sometimes hear). I explain the philosophy behind Dyson Spheres, and explain why dark matter can't be made out of antimatter.
00:00 Start
00:43 How big are really bright meteors?
04:15 Are Dyson Spheres just pure fantasy?
08:19 What would it take to resolve features on Proxima B?
11:32 Could anti-matter be dark matter?
12:23 Is Jupiter a failed star?
13:15 Would the transmit method let us detect planets in Andromeda?
14:55 Disappearing stars?
17:38 No more Ewok Forest?
18:50 Could a collider create a dangerous black hole?
20:57 Should we find Oumuamua?
23:21 Could we detect techno signatures in Andromeda?
24:45 What's happening on Mars?
27:43 Could we detect an extraterrestrial war?
28:54 Will space-based power work?
30:43 Will Mars be a knowledge-based economy?
32:53 Will we ever live on Venus?
33:21 Is the Moon moving away?
34:09 Does NASA have new space suits for Artemis?

Episode 744: Interview: Practical Time Travel with Prof. Ronald Mallet
In this special interview, I was fortunate to speak with Dr. Ronald Mallet, an emeritus professor at UConn. In addition to a lifetime's work in cosmology and astrophysics, Mallet has been trying to work out how our understanding of Einstein's theories of General Relativity might lead to a practical form of time travel.

Episode 711: The Universe in Formation. Hubble Sees 6 Examples of Merging Galaxies
10 billion years ago, galaxies of the Universe were ablaze with the light of newly forming stars. This epic phase of history is known as βCosmic Noonβ - the height of all star creation. Galaxies like our Milky Way arenβt creating stars at nearly the rates they were in the ancient past. However, there is a time when galaxies in the present can explode with star formation β when they collide with each other. This recently published collage of merging galaxies by the Hubble HiPEEC survey (Hubble imaging Probe of Extreme Environments and Clusters) highlights six of these collisions which help us understand star formation in the early Universe.

Episode 688: Remnants From the Early Universe. Primordial Black Holes
Black holes are already mind-bending enough. Matter and energy compressed into a region so dense that the escape velocity exceeds the speed of light. Places where space and time are tangled up so much that even if you could go faster than light speed, youβd still end up at the singularity.
Astronomers know of two kinds of black holes in the Universe: stellar mass and supermassive, and how we get them have been worked out pretty well.
But thereβs a third class of black hole, one which has never been observed nor detected indirectly, and yet it could explain some of the mysteries of the Universe, including the nature of dark matter.
Primordial black holes.

Episode 682: Life on Venus? A Key Biosignature Called Phosphine has been Discovered in Venus' Atmosphere
Well, did you hear the big news? Life on Venus. Lifeβ¦ on... Venus. Now, where have we heard this before? Oh right, life on Mars. If youβve been watching any of my videos or listening to Astronomy Cast, youβre cautiously optimistic. Skeptical, but hopeful.
Thatβs the right position to take, because buckle up, the internetβs about to run with this news. Itβs going to be difficult to figure out what was really discovered, and what this means for the search for life in the Universe.

Episode 676: Lunar Rovers. From Apollo to Artemis
When the Apollo astronauts first landed on the Moon, they couldnβt go far on foot. Thatβs why the three final missions were equipped with Lunar Roving Vehicles, or Moon buggies, which allowed the astronauts to cover much more ground and do more science.
Now that NASA is returning to the Moon by 2024 as part of its Artemis Program, itβs considering a fleet of new vehicles that will help astronauts roam far and wide across the surface of the Moon.

Episode 674: A Massive Star Just Disappeared. No Supernova, Just Straight to Black Hole
When the largest stars die, itβs usually pretty obvious. Supernovae are visible from billions of light-years away. But recently astronomers watched a massive star just disappear. No explosion, nothing, it justβ¦ vanished?
Of course, it could have been dust. Itβs always dust. But one intriguing possibility is that the star just imploded directly into a black hole, without the supernova detonation. And if thatβs the case, is this happening more often, we just didnβt notice it?

Episode 673: A New Way to Measure The Expansion of the Universe. The Cosmological Crisis Deepens.
This episode is a segment that we did in the Weekly Space Hangout talking about how astronomers are using masers (water lasers) to measure the expansion rate of the Universe.
You'd think that another, independent way to measure the expansion rate of the Universe would be helpful, but it's only deepened the mystery of the cosmological crisis.

Episode 670: NASA is Considering the Trident Mission. Going Back to Neptune and Triton.
Earlier this year, NASA announced 4 new Discovery-class missions that they were considering. These are low-cost, rapidly-built missions that will help scientists understand some mystery in astronomy and planetary science.
One of these missions is called Trident, and itβs going to be targeting the Planet Neptune. And more specifically, itβs going to be providing close up pictures of its largest moon Triton.

Episode 666: Two Confirmed Planets at Proxima Centauri. One in the Habitable Zone!
Astronomers have discovered thousands of exoplanets, and still need to confirm thousands more. And over the coming decades, weβll probably learn of millions of planets, orbiting stars weβve never heard of.
Thatβs why itβs reassuring to know astronomers are learning a tremendous amount about the closest star system to our own, Proxima Centauri. In fact, we now know of two planets orbiting the red dwarf star, one of which is in the habitable zone.

Episode 662: How Do We Know Black Holes Exist? With Dr Paul Sutter
Iβd say half the astronomy-related videos on YouTube are all about black holes. Clearly, theyβre a fascinating topic, but theyβre also a mystery. How do you observe something that can absorb all the radiation and matter falling onto them, and nothing can ever escape? How do we know theyβre really there, and what are the best observations we can make?
Today Iβm joined by Dr. Paul Sutter, a cosmologist, and astrophysicist to talk about how we know black holes are really there and not just a figment of an astrophysicistβs imagination?

Episode 660: Crew Dragon Reaches the Station. What it Took to Replace the Space Shuttle
On Sunday, May 31st, 2020, a SpaceX Crew Dragon capsule carrying astronauts Robert Behnken and Douglas Hurley docked with the International Space Station. This was a tremendous accomplishment for SpaceX and NASA, giving the United States the capability of launching its own astronauts, and no longer relying on its Russian partners.
This was the 5th time that US astronauts went into orbit on a new kind of space vehicle, following in the footsteps of Mercury, Gemini, Apollo, and the Space Shuttle.

Episode 656: Searching For Ice In The Moonβs Shadowed Craters
When youβre out in space, water is the most precious resource you can get your hands on. It can be used for air, water, to grow food, radiation shielding, and most importantly, as the propellant for your spacecraft.
Exploration of the Moon has revealed that thereβs a tremendous amount of water ice locked into the regolith, but itβs probably very difficult to access. But there are also permanently shadowed craters at the Moonβs poles that could have more than enough water to support a permanently inhabitable station on the Moon.
But itβs going to be tricky to get at, considering the fact that temperatures in the shadows plunge to -240 degrees Celsius, just 30 degrees above absolute zero.

Episode 653: Catching Interstellar Objects. What If We Could Explore Oumuamua Or 2I/Borisov?
The distances to other stars are depressingly enormous. Sure, itβs incredibly far to get to Mars, Jupiter, and even Pluto, but at least you can design a robotic spacecraft to make the journey and see the science results in your own lifetime.
But in the case of other stars, interstellar flight times will take thousands and even tens of thousands of years to send just a robotic mission.
Fortunately, the Milky Way has got our back. Other star systems have been hurling comets and asteroids towards the Solar System. All weβve got to doβ¦ is catch them.

The Moon orbits around the Earth. The Earth orbits around the Sun. And out in the distant Universe, astronomers have found a system that takes this logical progression to its most extreme. Thereβs a system where a supermassive black hole with millions of times the mass of the Sun orbits another black hole with billions of times the mass of the Sun.
How astronomers discovered this incredible interaction took careful observations, imagination, and the hard work of the Spitzer Space Telescope, taken during its final years of operation.

Episode 639: Waterworlds. Can There Be Life Without Land?
One of the longstanding questions astronomers have had is, are we normal? Is our Solar System a template for what we might expect to see as we look out into the Milky Way at other star systems?
As the data continues to come in, the answer to that question really seems to be no, weβre not normal. Star systems seem to have a huge variety of planets orbiting them. Familiar planets like our own terrestrial, gas and ice worlds. But then there are also super earths, mini-neptunes, hot jupiters.
And it looks like there are planets, located in their starβs habitable zone, which are completely covered with liquid water. Like, oceans which are dozens and maybe even hundreds of kilometers deep.
What would it be like on one of these worlds, and of course, we always want to know, could they be habitable?

Episode 635: Japan is Going to Bring a Sample of Phobos Back to Earth. The Martian Moon eXploration Mission
Mars has been the destination for so many of our spacecraft, and for good reason, itβs probably the most Earthlike place in the Solar System, with water ice on its surface and reservoirs of the liquid beneath the surface. If weβre going to find life, Mars might be the place.
But the tiny moons orbiting Mars, Phobos and Deimos, are scientifically fascinating on their own, and so far, a mission has never reached them.
Last week, Japan announced that theyβve greenlit their Martian Moon eXploration mission, or MMX, which will launch an orbiter, lander and maybe even a rover to Phobos in 2024, returning samples back to Earth by the end of the decade.

Episode 633: How Will Humans Return to the Moon in 2024? Lunar Lander Options for Artemis
After almost 50 years since the Apollo Moon landing missions ended, NASA announced that theyβre going to return to the surface of the Moon with their Artemis mission, ideally taking the first lunar footsteps in 2024.
NASA Administrator Jim Bridenstine asked for additional funding to achieve this goal, and the other branches of government havenβt been as enthusiastic about this plan. So donβt be surprised if the landing date slips to 2028 or even farther.
But NASA is moving forward on its architecture to return humans to the Moon, from its launch rocket to the entire method of getting astronauts down to the surface.
Exactly which rockets, modules and landing systems that will be used are still getting worked out, with different options still getting considered.

Episode 630: Betelgeuse Is Still Dimming! And We Have the Pictures to Prove It
Near the end of 2019, astronomers watching the red giant Betelgeuse noted how much the star had dimmed, continuing to steadily fade for months.
Itβs a variable star, and itβs known to get dimmer and brighter, but the big surprise is that itβs still continuing to dim, recently passing magnitude 1.56 and still getting dimmer. This is unprecedented in the decades that astronomers have been watching the star.
The worldβs biggest telescopes are on the case, and the European Southern Observatory released dramatic new images of Betelguese, resolving features on the starβs surface and surrounding area showing how itβs dramatically changed over the course of 2019.

Episode 629: Should We Fly to Another Star Soon? Or Wait for Better Technology to Come Along?
Itβs hard to really wrap your mind around the vast distances between stars. The fastest spacecraft ever launched into an interstellar trajectory right now is Voyager 1. If it was directed at the nearest star, it would take tens of thousands of years to make the journey across the interstellar gulf.
Even so, groups like Breakthrough Starshot and Icarus Interstellar are working on plans right now to try and send spacecraft to other stars, ideally within our lifetimes.
But we can see how quickly technology is advancing all around us, from materials science to high energy physics, not to mention reusable rockets.
It seems reasonable to ask, should we invest in an interstellar mission now, or wait a few decades or even centuries for better technology to come along which could make the trip much shorter?

Episode 627: We've Never Seen the Sun's Poles. That's About to Change With Solar Orbiter
On February 9, 2020, the European Space Agencyβs Solar Orbiter spacecraft launched from Cape Canaveral Florida on top of an Atlas V 411 spacecraft. The spacecraftβs mission is to fly inside the orbit of Mercury, on a tilted orbit that takes it above and below the Sun, capturing images of the Sunβs poles for the first time.
This is just a year and a half after the launch of NASAβs Parker Solar Probe, which will fly even closer. Together, the two spacecraft will measure the Sun from every angle up close, providing detailed images and insights of our closest star, to help understand how it creates and controls the giant bubble of plasma that surrounds the entire Solar System.

Episode 626: This is the Highest Resolution Image Ever Taken of the Sun
Youβre looking at the highest resolution image that has ever been taken of our Sun, using the brand new Daniel K Inouye Solar Telescope in Maui.
These lighter regions are convection cells, blobs of hot gas the size of Texas which have carried heat from deep below the surface of the Sun, releasing it into space. The darker lines are cooler regions, where the material is sinking back down into Sun.
This image is just a demonstration of the incredible power of this 4-meter observatory, which will join NASAβs Parker Solar Probe and ESAβs Solar Orbiter in ushering in the golden age of solar astronomy.

Episode 623: Escape! Spaceflight Abort Systems from the Launch Pad to Interplanetary Travel
On Sunday, January 19th, 2020, SpaceX launched a Falcon 9 rocket carrying its newly designed Crew Dragon spacecraft. 84 seconds into flight, at the moment of maximum aerodynamic pressure, the capsule fired its eight SuperDraco thrusters, detaching from the top of the rocket and flying ahead.
Moments after, the Falcon 9 rocket exploded in midair, destroying a completely good rocket, but the capsule was completely safe, jettisoning its trunk and landing gently in the ocean a few minutes later.
Nobody was on board the spacecraft, just a couple of test dummies, but this test proved that in the case of an emergency during the ascent stage fo the mission, Crew Dragon would be able to carry its astronaut crew to safety.

Episode 622: Finally! An Explanation for One of the Most Powerful Supernovae Ever Seen
In 2006, astronomers spotted the telltale sign of a supernova detonating in the galaxy NGC 1260, located about 240 million light-years away in the constellation of Perseus. As telescopes around the world turned their collective light-gathering power on the expanding explosion designated as SN 2006gy, they realized they were seeing something very unusual.
This clearly wasnβt a regular supernova. It grew to be 100 times brighter than the typical stellar explosion and lasted much much longer.
More than a decade after that cosmic explosion, astronomers finally think they know what series of events led to the release of this much energy, now called a superluminous supernova. A red giant ate a white dwarf. An event so rare it probably accounts for only 1 in 1000 supernovae.

Episode 620: Is There A Shadow Biosphere? Life On Earth That Isn't Related To Us
Whenever I talk about the search for life in the Universe and its emphasis on water, I get comments that scientists arenβt being creative enough. Why does life rely on water? Couldnβt there be lifeforms which are completely different from life on Earth? Isnβt that the textbook definition of alien?
Astrobiologists have only scratched the surface in their search for life in the Universe, and theyβre going after the low-hanging fruit. Since life on Earth can be found wherever thereβs water, why not check out the water on other worlds? If that doesnβt pan out, then theyβll expand the search.
But itβs possible there are aliens living right here on Earth among us, in a shadow biosphere, we just havenβt detected them yet.

Episode 618: The Future Of Gravitational Waves. Seeing Every Black Hole Collision In The Observable Universe?
In 2015, scientists discovered the telltale signal from ripples of spacetime sweeping over the Earth. It was the very first direct detection of gravitational waves, generated by the merger of two massive black holes 1.3 billion light-years away.
This discovery was the culmination of decades of research and construction of huge instruments called interferometers to detect the warping of spacetime caused by gravitational waves.
Today, the most advanced detectors, the LIGO/VIRGO collaboration, have turned up over 50 gravitational wave discoveries - on average one every week - allowing astronomers to perceive the Universe in a completely different way.
What new gravitational wave instruments are in the works, and what does the future hold for this relatively new field of study?

Episode 615: The Far Side Of The Moon Is The Perfect Place For a Radio Telescope
Weβve now passed the 50th anniversary of the Apollo 11 landing, and all eyes are back on the Moon. NASA is planning to return to the Moon by 2024 with its Artemis mission, the Chinese have put the Moon firmly in their plans for space exploration, and even SpaceX thinks the Moon is the perfect destination to test out the capabilities of its Starship.
But what can you do with the Moon? Refuel spacecraft with resources drawn from the lunar regolith? Mine its helium 3 for your fusion reactors? Build a lunar amusement park?
In fact, the far side of the Moon might make one of the best platforms we have for radio telescopes. One side of the Moon is completely blocked from Earthβs constantly increasing radio traffic, giving it the perfect view to the most sensitive radio signals in the Universe.

Episode 614: Starlink And Its Impact On Astronomy
On Monday, January 6th, 2020, another SpaceX Falcon 9 blasted off from Cape Canaveral, carrying another 60 Starlink internet communications satellites, bringing the full size of the constellation to 180. With just three launches, SpaceX becomes the largest satellite operator in the world.
But the company is just getting started. Theyβre planning to do this again every couple of weeks during 2020, bringing the total number of satellites in the constellation to about 1440, which is enough to provide high-speed internet services to the United States and parts of Canada.
Shortly after launch, as the satellites are raising their altitude, theyβre clearly visible to the eye as they streak across the sky in a close train.
Astronomers arenβt happy.

Episode 609: Why Haven't Aliens Settled Every Star In The Milky Way? With Adam Frank
At the American Astronomical Society's meeting Honolulu I got a chance to talk with Adam Frank about new research he's worked with Caleb Scharf, Jonathan Carroll-Nellenback and Jason Wright about the Fermi Paradox. They calculated how difficult it would be for aliens traveling at 10% the speed of light to settle the entire Milky Way, and it turns out, it's not as simple as you might think.

Episode 606: Betelgeuse Is Dimmer Than We've Ever Seen It
Over the last weekend, astronomy Twitter started noting that the red giant Betelgeuse, the prominent shoulder of Orion was looking visibly dimmer in the sky, and I had a few people reach out to me and ask me if it was really happening and if I knew what was going on.
This is exciting, of course, because Betelgeuse is living on borrowed time, and it could explode as a supernova any day now. Or, it might not detonate for another 100,000 years. We just donβt know.
Whatβs Betelgeuse up to? Is this a sign that itβs about to explode? And what would it mean if it did?

Episode 604: 100 Million Exoplanets By 2050? How Will We Get There?
As Iβm recording this video near the end of 2019, the total number of confirmed exoplanets stands at 4,104. Weβve come a long way since the discovery of the first exoplanet orbiting a sunlike star back in 1995 with 51 Pegasi b.
And the reality is that the race to find new exoplanets is only accelerating. New ground and space-based telescopes are turning up planetary candidates at an increasing rate. New techniques will find planets in entirely new ways. The bottom line is that over the next few decades, this mere 4000ish will multiply by orders of magnitude.
So letβs run the clock forward and try to calculate what the future holds for exoplanets. How many worlds will we know about 3 decades from now, in the year 2050?

Episode 603: What Is The Crisis in Cosmology? With Dr. Paul Sutter
How old is the Universe? In order to figure that out, all you have to do is figure out how quickly itβs expanding, and then the clock backward until everything is crunched together.
And astronomers have measured the rate that the Universe is expanding with tremendous precision at various times in its history; at the beginning, and much more recently. The problem is, these expansion rates disagree, but theyβve both been measured so accurately that their error bars donβt overlap.
In other words, there are multiple, highly accurate estimates for the age of the Universe, and they disagree.

Episode 602: Q&A 110: Why Can't I Just Be Realistic About Mars? And More...
In this week's questions show, I explain why I don't think we always need to be realistic, if galaxies in the local group are bound together gravitationally, and what we should call Earth-moving equipment on Mars.
00:20 Be realistic.
04:24 Are galaxies in the local group bound?
05:56 Will gravitational waves give us advanced notice of collisions?
08:36 Will we ever be able to live outside on Mars?
10:16 Are we going to ruin Mars too?
12:42 Mars-moving equipment?
14:07 Could the Moon have an atmosphere?
15:51 Liquid water on the surface of Mars
16:49 Is there a business case for Mars?
19:17 What about nitrogen?
21:21 What will need to come from Earth?
23:06 Are there planets with less gravity than Earth?

Episode 601: Living Off The Land On Mars. What Can We Find On The Red Planet?
Extending humanity to other worlds in the Solar System is at the very limits of our modern technology. And unless there are dramatic discoveries in new propulsion systems or we learn how to build everything out of carbon nanotubes, the future of space exploration is going to require living off the land.
The technique is known as In-Situ Resource Utilization or ISRU, and it means supplying as much of your mission from local resources as possible.
And many of our future exploration destinations, like Mars, have a lot to work with. Letβs look at the raw materials on Mars that missions can use to live off the land and the techniques and technologies that will need to be developed to make this possible.

Episode 599: Flying In The Cloudtops Of Venus. Balloons, Airships And Airplanes For Venus
The exploration of Venus has been mainly about getting down to the surface of the planet. The Soviet Union sacrificed lander after lander to discover just how extreme the conditions are down there on the ground.
But higher up, among the clouds, the climate on Venus is surprisingly Earthlike in temperature and pressure, and there have been some fascinating ideas for robotic and human explorers to fly the skies of Venus, to help understand our evil twin planet.
Letβs take a look at them.

Episode 594: Building Space Telescopes... In Space
When it comes to telescopes, bigger is better. Thatβs true down here on Earth, and itβs especially true out in space. As astronomers and engineers design the next generation of giant space telescopes, theyβre running up against the limits of current launch providers. There are only so many ways you can fold a huge telescope to get it to fit inside a 5-meter launch fairing.
The upcoming James Webb Space Telescope is pretty much the very limit of what you can construct on Earth and put into space in a single launch. To go bigger, space agencies will need to consider assembling their next-generation space telescopes⦠in space.

Episode 591: The History And Future Of The James Webb Space Telescope
On March 30, 2021, NASAβs James Webb Space Telescope will blast off from the European Space Agencyβs European spaceport in Kourou, French Giana on board an Ariane 5 rocket.
Itβll fly to the Sun-Earth L2 Lagrange point, a relatively stable spot in space that keeps the glare from the Sun, Earth, and Moon all in a tiny spot in the sky. Then, itβll unfurl its tennis court-sized sunshade, fold out its gigantic 6.5-meter mirror, and peer out into the distant cosmos.
Over the course of the next 10 years, this infrared observatory will help astronomers learn about the earliest moments of the Universe, directly observe the atmospheres of planets orbiting other stars, and peer at newly forming stars and planets.
And if you listened to the words I just said with equal parts terror and skepticism, I donβt blame you. James Webbβs path to space has been long and tortuous. And the risks that the mission still faces are very real. Hopefully, the science will be worth it. Hopefully, nothing else goes wrong from now until deployment.
So today, I want to do a deep dive into James Webb. To talk about the history of the mission, why it exists, how the development went, and where it stands today.
Iβll warn you though, the length of this video is going to go way over budget.

Episode 587: Why Launch Solar Panels When You Can Print Them Directly In Space? Printing Perovskite Panels
Solar energy is the ideal way to power a spacecraft. Thereβs no weather, thereβs no pesky atmosphere, just pure photons streaming from the Sun to harvest for whatever you need. Well, as long as youβre within the inner Solar System.
But solar panels are complicated and fragile made of sensitive electronics and glass - not to mention, really heavy. Any spacecraft equipped with solar panels needs to handle the gravity down here on Earth for the construction and testing, then the shaking and high Gs of launch. The solar panels need to unfold perfectly once they get to space. And the total amount of energy you can harvest is limited by the size of your rocketβs launch fairing.
Maybe thereβs a new strategy. NASA is currently funding research into a new type of solar panel that can be carried into space as a liquid and then sprayed onto a surface to turn it into a power generating surface.

Episode 585: Can Life Spread From Star to Star? The Theory of Galactic Panspermia
The race is on to find life in other places in the Solar System, from underground reservoirs on Mars to the subsurface oceans on Europa and Enceladus.
If spacecraft, rovers or even astronauts make the momentous discovery of life on another world, thatβll just open up new questions. Did it originate all on its own, completely independently from Earth, or are we somehow related? And if we are related, how long ago did our evolutionary trees branch away from each other.
Even though Mars is millions of kilometers away, it could be possible that weβre still related thanks to the concept of Panspermia; the idea that meteor impacts could transfer rocks and maybe even living creatures from world to world.
But could you go one step further? If we find life on another star system, could we discover that weβre actually related to them too? Is Galactic Panspermia possible?

Episode 584: Surviving On Venus. Is It Time To Go Back To That Awful Place?
If youβve watched this channel enough, you might have the impression that I hate Venus. Itβs possible, just possible Iβve even suggested that the planet is so terrible it should be pushed into the Sun.
The reality, of course, is that itβs an absolutely fascinating world - the closest twin to the Earth that we have in the Solar System. Itβs nearly the same mass and has the same surface gravity.
While Earth is the beautiful life-filled world we all enjoy, Venus is a tortured hellscape, with temperatures hot enough to melt zinc. With atmospheric pressures more than 93 times what we experience here on the surface of Earth. And I always forget about the sulphuric acid rain.
The Soviets sent a series of landers to a horrible demise for a glimpse of the surface of Venus in the 70s and 80s. But nobodyβs been back since.
There have been new techniques and technologies in development that might make a serious exploration of the surface of Venus possible again. Exploration that could help us understand why the planet went so horribly horribly wrong.

Episode 583: A Single Spacecraft Will Visit Seven Asteroids. NASA's Lucy Mission Passes Its Design Review
Scientists have had the opportunity to examine several asteroids in the Solar System now, and what theyβve learned is how much variety is out there, depending on the mass, distance from the Sun and composition.
Astronomers currently know of 829,400 asteroids across the Solar System, and theyβd love to visit as many of them as possible to learn more about them.
Considering the price of a single spacecraft, thatβs going to get expensive. Fortunately, there are places in the Solar System that have trapped a large number of asteroids in a way that a single spacecraft can visit several of them as part of a mission.
Theyβre at Jupiterβs L4 and L5 Lagrange points, and this week NASA approved a new mission thatβll explore 7 different asteroids over a 12-year journey.
Itβs called Lucy.

Episode 582: Q&A 104: Should We Reconsider The Definition Of A Moon? And More...
In this week's questions show, I explain why it's probably not time to reconsider the definition of a moon, if we could make artificial gravity with a chunk of a neutron star, and why a supermassive black hole isn't the anchor for an entire galaxy.
00:47 Should we reconsider the definition of a moon?
03:35 Could we make artificial gravity with mass?
05:48 Why didn't the Big Bang collapse back into black hole?
07:47 Why can't a black hole be the anchor of the galaxy?
10:45 How far and how small can we see?
13:37 What is left after a black hole evaporates?
15:00 Could you have a star made out of something else?
16:32 Could a planet orbit a binary star?
18:29 Could aliens Planet 9?
19:24 If aliens are advanced, we're no threat
21:35 How can aliens not exist?
22:30 Why don't they put a microscope in a rover?

Episode 580: Is Humanity Prepared To Discover Alien Life?
People always ask me how I think humanity will react if we discover life somewhere out there in the Universe, whether itβs bacteria under the surface of Mars, a biosignature of alien life in the atmosphere of another world, or a radio signal from another civilization.
Will our civilization lose its collective mind and have a temper tantrum on a global scale? Will we become one of those purge planets from Rick and Morty?
Will the discovery suddenly end all religion, as we wait for guidance from our new alien overlords?
Will we gather together as a species to present a common front to whatever cosmic horrors await us beyond the Solar System?
In my opinion, if I could sum up the collective response in a single word, it would be: meh.

Episode 577: AstroClipper: Plans For A Two-Stage, Fully Reusable Spaceplane
Even as the first rockets were launched into space decades ago, aerospace knew it was a wasteful process. Rocket stages, motors, and complex equipment crashed into the ocean or burned up in the Earthβs atmosphere.
Could spaceplanes bring the costs down? Flying to orbit with a combination of jet engines and rockets and then safely re-enter the Earthβs atmosphere again.
Single-stage to orbit spacecraft and spaceplanes have always seemed out of reach, and actually not that practical. But what about a two-stage, fully reusable spaceplane?
Exodus Space Corporation has been secretly working on this concept for a decade now, and what theyβre proposing is pretty revolutionary.

Episode 574: Venus Could Have Supported Life For Billions Of Years. First Habitable Planet In The Solar System?
After decades of research, including multiple landers and orbiters, science can definitively say: Venus sucks. Seriously, that place is the worst, with its boiling temperature, intense pressure, sulfuric acid rain, and more.
But was it always this bad? According to new research from NASA and various universities in Sweden and the US, Venus might have actually been the first habitable world in the Solar System. And it might have maintained a reasonable climate for billions of years, finally rolling over into a runaway greenhouse effect just a few hundred million years ago.

Episode 571: Starship Takes Shape. Are We Months Away From A Fully Reusable Rocket System?
On Saturday, September 28th, SpaceX CEO Elon Musk stood in front of an audience in Boca Chica, Texas, and presented the fully assembled SpaceX Starship, 50 meters tall and made from shiny stainless steel.
As part of his presentation, Musk showed off the history of the companyβs developments so far and gave us an updated view of what Starship and its first stage Superheavy booster will look like when theyβre fully operational.
It was actually a pretty short presentation, and there werenβt a lot of details. But he stuck around to answer questions from many space journalists, and weβve got a much better idea about Starship and what happens next.

Episode 570: What Will It Take To Feed A Million People On Mars?
In 2017, Elon Musk laid out his grand sweeping plans for the future of SpaceX, the company that would take humanity to Mars. Over decades, tens of thousands of Starship flights would carry a million human beings to the surface of the Red Planet, the minimum Musk expects itβll take to create a self-sustaining civilization.
The number of details in an effort like this is mind-boggling. What about the reduced gravity, radiation exposure, and space madness? What about return flights? Replacement parts? Building materials?
Whatβs everyone going to eat?

Episode 569: Open Space 46: Dr. Robert Zubrin and the "Case for Space"
One of my most requested guests is Dr. Robert Zubrin, engineer and founder of the Mars Society. It was Dr. Zubrin's "Case for Mars" that helped inspire me to get into space journalism in the first place. We had a wide-ranging interview that updated the Case for Mars, looked at what comes next, and how current efforts are stumbling in their efforts to return humans to the Moon, and then on to Mars.

This week I was joined in a livestream with Dr. David Kipping from Columbia University. We had a great interview about his research into exomoons, what new observatories will do for this field. We also talked about his idea of the Terrascope, using the Earth's atmosphere as a lens to study the Universe. And we talked about how scientists can better use the internet to communicate directly with the public about their research.

Episode 566: Better Than Earth? Are There Superhabitable Worlds In The Milky Way?
Iβve said many times in the past that the Earth is the best planet in the Universe. No matter where we go, weβll never find a planet thatβs a better home to Earth life than Earth. Of course, thatβs because we, and all other Earth life evolved in this environment. Evolution adapted us to this planet, and itβs unlikely we could ever find another planet this good for us.
However, is it the best planet? Are there places in the Universe which might have the conditions for more diversity of life?

Episode 563: Want To Explore Mars? Send Humans To The Moons Of Mars First: Phobos And Deimos
Humans to Mars. Thatβs the plan right? The problem is that sending humans down to the surface of Mars is one of the most complicated and ambitious goals that we can attempt. Itβs a huge step to go from low Earth orbit, then lunar landings, and then all the way to Mars, a journey of hundreds of millions of kilometers and 2 years at the least.
But there are two places humans can go which are a stepping stone between Earth and Mars. Base camps that would let us gather our resources in relative safety before dropping down into that gravity well.
Iβm talking about the moons of Mars: Phobos and Deimos.

Episode 561: Water Vapor Seen In the Atmosphere Of An Exoplanet. It Might Even Be Rain
Weβre learning more and more about extrasolar planets, and for the first time, astronomers have discovered water vapor in the atmosphere of a planet orbiting another star. The planet is located in the habitable zone of its star, so this might even be rain.
Of course, itβs not all good news, itβs much more massive than Earth, with higher gravity, and is probably bathed in radiation from its red dwarf star. But, itβs a good start in the search for habitable places in the Universe, places where there might be life.

Episode 558: A Tour Of The Lagrange Points. Part 3 - Trojans and Space Colonies at L4/L5
Weβve reached the third part of our series on Lagrange Points, those stable spots in the Solar System, where you can sort of hover with the minimum amount of fuel.
This episode weβre going to look at the L4 and L5 points which share the orbit with a more massive object.

Episode 556: A Tour Of The Lagrange Points. Part 2 - Space Telescopes At L2 And Nothing At L3
Lagrange Points. Stable spots in space that you just canβt stop thinking about. What spacecraft work best in which places? What are some amazing ideas that could utilize these regions across the Solar System?
In the last episode, I gave an overview of the Lagrange points, and then went into the details of spacecraft missions sent to L1, the perfect place to constantly observe the Sun, the Earth, or to block radiation coming from the Sun. The best place for a lunar elevator, or a spot to put a space station at the Moon.
This week, weβre going to talk about L2 and L3, the other meta-unstable spots that you can park a spacecraft at.

Episode 555: A Tour Of The Lagrange Points. Part 1 - Past And Future Missions To L1
Thanks to gravity, there are places across the Solar System which are nicely balanced. Theyβre called Lagrange Points and they give us the perfect vantage points for a range of spacecraft missions, from observing the Sun to studying asteroids, and more.
Various spacecraft have already visited Lagrange Points, used them for some or all of their missions, and there are fascinating plans in the works that could put new missions and even space colonies into these balanced places in the Solar System.
Letβs explore the Lagrange Points.

Episode 553: Bringing Mars To Earth. The Plans For a Mars Sample Return Mission
One of the great accomplishments of the Apollo missions was to bring home hundreds of kilograms of lunar rock. Suddenly, geologists had a lifetimeβs worth of lunar samples captured from several different spots across the Moon. These rocks and dust have been under continuous analysis since the Apollo 11 astronauts came home over 50 years ago.
And theyβre still making discoveries.
Scientists have samples of the Sunβs solar wind, particles from a cometβs tail, a few grams from an asteroid, with more coming shortly.
But thereβs one world, the focus of so much scientific study, which has never had a sample returned: Mars.
NASA and the European Space Agency have been making plans to bring a sample home from Mars for decades, and now, missions could fly in the next few years, finally bringing a chunk of the Red Planet home to Earth for us to study directly.

Episode 552: A Spacecraft Is Going To Build Its Own Solar Panels In Space: Archinaut One
As Iβve mentioned in several episodes now, humanity is in a bit of a transition period, a time when it makes sense to launch material up and out of Earthβs gravity well into orbit, and beyond. But itβs really expensive, costing up to $10,000 per pound you want in orbit, and 10 times if you want it on the Moon.
But over the coming decades, more and more of our space-based infrastructure will be built in space, manufactured out of materials that were mined in space.
The only thing thatβll actually need to leave the Earthβs clingy gravity well will be us, the humans, the tourists, wanting to visit all that space infrastructure.
Of course, in order to achieve that space future, engineers and mission planners will need to design and construct the technology that will make this possible.
That means testing out new prototypes, technologies and methodologies for mining and space-based manufacturing.

Episode 550: Exploring The Icy Moons of Jupiter. NASA's Europa Clipper and ESA's JUICE
Mars is the place that most of our spacecraft, landers and rovers are studying, searching for any evidence that life ever existed somewhere else in the Solar System.
But talk to planetary scientists, and theyβre just as excited about the ocean worlds of the Solar System; the moons, asteroids, dwarf planets and Kuiper Belt objects where there could be vast oceans of liquid water under thick shells of ice.
The perfect environment for life to thrive.
Weβve only had tantalizing hints that these oceans are there, but NASA is building a spacecraft that will study one of these worlds in detail: the Europa Clipper. And theyβre not the only ones. The European Space Agency is building their own mission, the Jupiter Icy Moons Explorer.

Episode 549: Why Build Big Rockets At All? Itβs Time For Orbital Refueling
On Tuesday, July 30th, NASA announced 19 different partnerships with 13 different companies to use their expertise to help them develop space technologies, from advanced communications systems to new methods of entry, descent and landing.
Instead of contracting out specific projects, NASA will make its employees, facilities, hardware and software available to these companies, for free.
One of the most notable of these partnerships will be with SpaceX and NASAβs Glenn and Marshall Centers to help advance the technology of transferring propellant in orbit.
In other words, NASA is going to help SpaceX figure out how to refuel a spacecraft while itβs in space. And if they can figure this out, it could completely change the way missions are launched and flown.

Episode 547: Spacecraft Gyroscopes And Reaction Wheels. You Can Never Have Enough
Itβs amazing to think there are telescopes up in space, right now, directing their gaze at distant objects for hours, days and even weeks. Providing a point of view so stable and accurate that we can learn details about galaxies, exoplanets and more.
And then, when the time is up, the spacecraft can shift its gaze in another direction. All without the use of fuel.
Itβs all thanks to the technology of reaction wheels and gyroscopes. Letβs talk about how they work, how theyβre different, and how their failure has ended missions in the past.

Episode 546: One Year, Almost 1,000 Planetary Candidates. An Update On TESS
NASAβs Transiting Exoplanet Survey Telescope launched back in April, 2018. After a few months of testing, it was ready to begin mapping the southern sky, searching for planets orbiting stars relatively nearby.
Weβre just over a year into the mission now, and on July 18th, TESS has shifted its attention to the Northern Hemisphere, continuing the hunt for planets in the northern skies.
As part of this shift, NASA has announced a handful of fascinating new planets turned up by TESS, including a couple of worlds in categories which have never been seen before.
Farewell Kepler, Welcome TESS

Episode 543: What Are Light Echoes? Using Reflections Of Light To See Even Further Back In Time
When we look outward into space, weβre looking backwards in time. Thatβs because light moves, at the speed of light. It takes time for the light to reach us.
But it gets even stranger than that. Light can be absorbed, reflected, and re-emitted by gas and dust, giving us a second look.
Theyβre called light echoes, and allow astronomers another way to understand the Universe around us.

Episode 542: How Habitable Is Titan? NASA Is Sending The Titan Dragonfly Helicopter To Find Out
There are few places in the Solar System which are as fascinating as Saturnβs moon Titan. Itβs a world with a thicker atmosphere than Earth. Where itβs so cold that it rains ammonia, forming lakes, rivers and seas. Where water ice forms mountains.
Like Europa and Encleadus, Titan could have an interior ocean of liquid water too, a place where there might be life.
Titanβs got layers, and fortunately, thereβs an awesome new mission in the works to explore it: the Titan Dragonfly mission.

Episode 541: Why Is The Moonβs South Pole So Important? Itβs All About Water
As NASA prepares to return to the Moon by 2024 as part of its Artemis program, the agency is focusing its efforts on exploring the Moonβs polar regions. These are areas of the Moon which seem to have a lot of water mixed in with the regolith.
Some of these craters are permanently in shadow, and might still have large quantities of water, thatβs accessible to human and robotic explorers. This is a critical resource, and the Moon might be just the place to help humanity as it pushes out to explore the rest of the Solar System.
But it might also be an illusion. We really wonβt know until we look up close.

Episode 540: Planetary Society Deploys LightSail 2βs Solar Sail. What Does The Future Hold For Solar Sails?
Where you can travel in space depends on how much propellant youβve got on board your rocket and how efficiently you can use it. But thereβs a source of free propellant right here in the Solar System - the Sun - which is streaming out photons in all directions. You just need to catch them.
And right now, the Planetary Societyβs new LightSail 2 spacecraft is testing out just how well itβll work.

Episode 537: Catching The Next Interstellar Asteroid Or Comet. ESA's Comet Interceptor Mission
On October 19th, 2017 astronomers detected the first interstellar asteroid (or maybe comet) passing through the Solar System: Oumuamua. It had a brief encounter with the inner Solar System and then hurtled back out into interstellar space.
Once astronomers noticed it, they directed the worldβs telescopes on the object, but it was too far away to reveal anything more than a faint dot.
Until now, weβve only been able to study objects in our own Solar System. We have no idea what the rest of the Milky Way is like.
But we were too late to catch it, no spacecraft was ready to make a quick intercept.
Well, scientists arenβt going to make that mistake again. The European Space Agency announced their plans to build a comet interceptor. A spacecraft that will lurk out at the Earth-Sun L2 Lagrange point, waiting for a long-period comet or interstellar object to pounce on, and give us the first close up view ever.

Episode 538: Searching For The Red Edge. How The Earth's Forests Are Telling The Aliens Where We Live
People are always worried that alien civilizations will detect the transmissions from our old radio shows and television broadcasts, and send in the invasion fleet. But the reality is that life itself has been broadcasting the existence of life on Earth for 500 million years.
Blame it on the plants.
In addition to filling the atmosphere with oxygen, plants give off a very specific wavelength visible in infrared radiation. Itβs the kind of signal that other civilizations could search for as theyβre scanning the galaxy.
Itβs what weβll be looking for too.
But donβt just blame the plants. Other forms of life have been giving off signals too, signals we can search for as we discover new exoplanets and wonder if they have life there.

The Solar System is a really big place, and it takes forever to travel from world to world with traditional chemical rockets. But one technique, developed back in the 1960s might provide a way to dramatically shorten our travel times: nuclear rockets.
Of course, launching a rocket powered by radioactive material has its own risks as well. Should we attempt it?

Episode 530: 386: Planetary Protection: What If We Destroy Life Before We Even Find It?
Explorers have always brought stowaways with them on board. Thanks to our travels around the world, hardy creatures like rats, goats, pigs and starlings and more have found their way to every corner of the globe. Not to mention our plants, microbes and viruses.
Wherever we go, life goes with us, whether we want it to or not. And when we travel to other worlds, it looks like the most extreme life Earth has ever cooked up is ready and willing to make the journey with us.
Now that the big flybys are over, itβs time to dig into the regolith, search for life in underground lakes and oceans, return samples back to Earth. Weβre going to give life every opportunity to contaminate other worlds.
What can we do to prevent it?

Episode 457: 361: Making the Atmosphere Disappear. The Power of Adaptive Optics
The Earthβs atmosphere keeps us safe from the harsh environment of space, but it also obscures our view into the cosmos. No matter how powerful a telescope you build, the turbulence of the atmosphere limits your resolution. But astronomers and engineers have an amazing technology that allows a telescope to peer into space as if the atmosphere isnβt even there, producing images from here on the ground which are as sharp and clear as if the telescope was out in space. Itβs called adaptive optics, and weβre now at the point where the most powerful ground-based telescopes have matched and even exceeded the capability of space telescopes.
