Episode 185: Did a Supernova Cause a Mass Extinction?, with Brian Fields
Feature Guest: Brian Fields By now we are all familiar with the theory that an asteroid brought to an end the age of the dinosaurs, a period of domination that had lasted 167 million years. But asteroids are not the only harbingers of doom that lurk in the darkness of space. Today we’re joined here at The Star Spot by Brian Fields, whose research team has found evidence linking supernovae events in deep space to mass extinction events in deep time. Current in Space Tony reports on the mystery of the vanished star. Then Jeff describes electromagnetic flare from a gravitational wave event caused by two merging black holes. And Camilla brings news of two new super-Earths. Finally Amelia and Priyanka offer an explanation for radio waves caused by pulsars.

Episode 184: The Milky Way's First Fast Radio Burst, with Sandro Mereghetti
Feature Guest: Sandro Mereghetti Fast radio bursts are a new mystery in astronomy. These highly energetic events of unknown origin were first discovered in 2007 out in deep space. Now a team is reporting the first fast radio burst to emanate from our own Milky Way Galaxy. Today we’re joined here at The Star Spot by Sandro Mereghetti, whose team is on the hunt for the source of this unusual phenomenon. Current in Space Camilla shares the remarkable discovery, or rather re-discovery, of the heartbeat of a supermassive black hole in a distant galaxy, found still alive and kicking ten years after being first observed. In addition to the supermassive black hole shaping the environment at the centre of our home galaxy, Amelia and Priyanka explain that something else there is also calling the shots (and no, it's definitely not like what we saw in Star Trek V). In other black hole news, Finally, Jeff brings us back down to Earth (though still above Earth), as SpaceX is launching ever more Starlink satellites into orbit to provide high-speed Internet coverage to citizens of our planet. There's only one problem: the future of ground-based astronomy may be at stake. About Our Guest Sandro Mereghetti is research staff member at the National Institute for Astrophysics in Milan.

Episode 182: Planet Nine or Black Hole One, with Jakub Scholtz
Feature Guest: Jakub Scholtz We’ve long believed that membership in the solar system’s planetary family was limited to those eight planets we learned about in grade school. But then astronomers began to raise the possibility of a new super-Earth-sized planet, five to ten times the mass of Earth, orbiting far off in the outer solar system. Now if you thought the concept of Planet Nine was astonishing, consider if the mysterious body wasn’t a planet at all - but a black hole. That’s right, Planet Nine might be Black Hole One, our own solar system’s very first singularity. Today we’re joined here at The Star Spot by astrophysicist Jakub Scholtz, co-author of a new study making the case for this fascinating proposal. Current in Space Tony celebrates the 30th anniversary of the Hubble Space Telescope. Then Jeff reports on water loss from mysterious interstellar comet Borisov.

Episode 180: Wormholes through Space and Time, with John Cramer
Feature Guest: John G. Cramer They are the stuff of science fiction, but wormholes are also the subject of intense scientific debate. Can wormholes provide a mechanism for faster than light travel through space and, even more intriguing, do they open the door to travel through time? Today we’re joined here at The Star Spot by one of the world’s foremost authorities on wormholes, Professor John G. Cramer, to share results from his thought experiments on wormholes and his laboratory experiments aimed at changing the past. Current in Space Jeff starts us off with a bang... the largest bang we've ever seen in the universe. Then Camilla unveils the name of the next generation Mars rover.

Episode 179: Dreams of Floating Cities, with Geoffrey Landis
Feature Guest: Geoffrey A. Landis When we think of terraforming, we probably envision turning the Red Planet blue. But Mars isn’t the only world in our solar system that ambitious scientists have considered transforming. Imagine a network of floating cities in the clouds of Venus, or sailing ships plying the oceans of a newly thawed moon in the outer solar system. Today we’re going to dream here at The Star Spot with NASA scientist and award-winning science fiction author, Geoffrey Landis. Current in Space After NASA's InSight lander touched down on Mars in late 2018, it's already gathering fascinating data, but as Camilla explains, its latest discovery is literally groundshaking: Mars is officially a seismically active planet! Then Jeff reports on the launch of Solar Orbiter, a new Sun-exploring spacecraft that will enhance our knowledge of the Sun's influence on the entire Solar System. And while Pluto's heart made us fall in love with the famous dwarf planet all over again, Anshool describes an influence that goes far beyond its aesthetic qualities. Wrapping it up with a special double bill on our local star: The most detailed image so far of the Sun's surface has been captured, and Amelia and Priyanka provide the details.

Episode 178 Sibling Rivalry at the Centre of the Galaxy, with Smadar Naoz
Feature Guest: Smadar Naoz We’ve long known that most galaxies contain at their core a supermassive black hole that can be millions of times the mass of the sun. But now researchers are discovering galaxies with more than one supermassive black hole at their centre. To understand the implications of this discovery and what it could mean about the history of the Milky Way, should our own galaxy be among this collection, today we’re joined here at The Star Spot by astrophysicist Smadar Naoz. Current in Space Stars like the Sun are a no-brainer when it comes to finding habitable planets, but Amelia and Priyanka say another star is even better; say hello to the orange dwarf. In other habitable planet news, Jeff reports on the discovery of two super-Earth exoplanets that just may be home to life. Finally, Anshool looks to the ancient history of our own planet with the finding of the oldest known asteroid impact, one which may have marked a major climate shift. About Our Guest Smadar Naoz is Howard and Astrid Preston Term Chair in Astrophysics and Associate Professor of Physics and Astronomy at UCLA.

Episode 177: The Case of the Missing Dark Matter, with Guo Chi
Feature Guest: Guo Qi Dark matter vastly overshadows ordinary matter in our universe. Wherever astronomers turn their telescopes they find galaxies dominated by dark matter. But all that changed recently with the first discoveries of dwarf galaxies suspiciously deficient in dark matter. To make sense of this baffling finding and how it relates to our Milky Way’s own local dwarf galaxies, today we’re joined here at The Star Spot by study lead Professor Guo Qi from the Chinese Academy of Science. Current in Space NASA's newest planet hunter has made its most remarkable discovery yet: an Earth-sized world in its star's habitable zone, and Anshool provides everything you need to know. Amelia and Priyanka explain a mystery surrounding a particle, and a strange halo around a pulsar may be the key to solving it. And in his debut, Jeff offers more pulsar news in that a new surface map of a particular pulsar may question everything we thought we knew about these lighthouses of the Galaxy. About Our Guest Guo Qi is Professor of Astronomy at the National Astronomical Observatories of the Chinese Academy of Science. She received her PhD from the Max-Planck Institute for Astrophysics and held a Postdoctoral Fellowship at the UK’s Durham University.

Episode 176: Second Genesis, with Jay Melosh
Feature Guest: Jay Melosh If we should find creatures crawling around Titan or swimming under the ice sheets of Europa or Enceladus, they will almost certainly turn out to be the result of a second genesis, those creatures truly alien in the most profound sense. That startling conclusion follows from a series of groundbreaking simulation that found it exceedingly unlikely that life can be successfully transferred between the worlds of our solar system. To unpack the significance of this conclusion, today we’re joined here at The Star Spot by geophysicist Jay Melosh, who caused an uproar when he presented his findings at a recent meeting of the American Geophysical Union. Current in Space Tony does triple duty. He opens with his own 2019 retrospective, featuring a review of some of the impressive achievements made in space science, and to expect more of the same in 2020. Then he and Joseph excite with possible exploration methods for two ocean worlds in the outer Solar System. And for those of you who missed the spectacular "ring of fire" solar eclipse in the eastern hemisphere, Tony and Anshool have you covered, with a review of places impacted, and a preview of similar events in the near future. About Our Guest Jay Melosh is University Distinguished Professor of Earth and Atmospheric Science at Purdue University. He is the recipient of the Leon Blitzer Teaching Award, the Hess Medal of the American Geophysical Union, and the Humboldt Prize Fellowship, among many other honours.

Episode 175: The Truth is Out There (at the University of Manitoba)
Feature Guest: Shelley Sweeney The University of Manitoba has just acquired the largest collection of UFO related material. Prominent Canadian ufologist Christ Rutkowski has made a donation of over 30,000 documents, photos, artifacts and government reports, including files relating to the famous 1967 Falcon Lake Incident, involving a purported physical contact with a mysterious craft. Whether you’re intrigued by the phenomenon of belief or you believe in the phenomenon, the extraordinary human effort to address the UFO question is worth our attention, argues Shelley Sweeney, Head of Archives & Special Collections at the University of Manitoba, who joins us here at The Star Spot. Current in Space In her final broadcast, Dunja literally goes out with a bang as bizarre eruptions of particles have been seen on the asteroid Bennu by orbiting spacecraft OSIRIS-REx. Then Joseph looks back at our own planet, with a remarkable discovery: a new map of Antarctica that could forecast the future impact of climate change. In his debut, Anshool describes a star careening through space, shot out by the supermassive black hole at the center of the Milky Way! In other supermassive black hole news, Amelia and Priyanka share a finding that shall surely change the way we understand how huge galaxies form: a galaxy with three supermassive black holes! Finally Tony breaks down two new images of the first interstellar comet ever observed by humanity!

Episode 174: Fuzzy Dark Matter, with Lachlan Lancaster
Feature Guest: Lachlan Lancaster Quantum mechanics is strange. Until recently we could comfort ourselves with the belief that its odd properties were safely confined to the world of the microscopic. But what if quantum mechanical effects were suddenly magnified to cosmological scales. Imagine the quantum mechanical interference pattern spread across clusters of galaxies. That’s a possibility, according to a new theory of dark matter known as fuzzy dark matter, which imagines dark matter particles as being incredibly minuscule but with astrologically large wavelengths. How can we prove whether this fascinating new theory is correct? Do these ultra small particles give us clues to mysterious string theory? And what does all this mean about the past, present and future of the universe? Today we’re joined here at The Star Spot by Lachlan Lancaster, co-author of a new paper that sheds light on these questions. Current in Space While NASA's New Horizons spacecraft transformed Pluto from a speck to a world before speeding past, Joseph gets us excited for a proposed second mission that would orbit the dwarf planet and more! Then Dunja asks if a certain particle may be changing the very fabric of the Universe itself! And Amelia and Tony take us back in time to the early Universe with a baffling discovery: the first stars may have formed faster than previously thought. About Our Guest Dr. Lachlan Lancaster is an astrophysics PhD student at Princeton University studying the intersection of Galactic Dynamics and Cosmology. He receiverd his Masters from Cambridge University after conducting research at the University of California Davis.

Episode 173: Discovering an Ancient Oasis, with William Rapin
Feature Guest: William Rapin Welcome to Sutton Island, here in the middle of a beautiful and rugged landscape consisting of shallow lakes filled with salts and minerals. It’s a common vista on this world, and while the world in question is not our home, ancient Mars may well have been someone’s home. Today we’re joined here at The Star Spot by William Rapin, with reports from the latest discoveries of the Mars Curiosity rover and why one of the Principal Investigators of NASA’s Viking mission is now convinced we found life on Mars back in the 1970s, Current in Space Amelia and Tony share exciting news: the most powerful radio dish telescope in the world will soon be ready for widespread astronomical use! Then Joseph excites even more with a stunning discovery: the presence of water in the atmosphere of an exoplanet, making it the most prominent target yet in the search for habitable worlds. And once again on the subject of habitable worlds, in her debut, Dunja wonders if the size of planets matters to their potential for being habitable. Finally, Amelia and Priyanka report on a remarkable new technique for estimating the mass of black holes! About Our Guest William Rapin is postdoctoral scholar in the Division of Geological and Planetary Sciences at Caltech. His research investigates the surface geochemistry of planets to improve our understanding of their origin, evolution, and habitability.

Episode 172: The Hubble Not-So Constant
Feature Guest: Sherry Suyu The Hubble constant, which measures the expansion rate of the cosmos, may not be a constant after all, and if that’s true it means we’re missing something big in our understanding of the universe. Today we’re joined here at The Star Spot by Sherry Suyu, who leads the aptly named H0LiCOW project which uses the phenomenon of gravitationally lensed quasars to measure the expansion rate of the universe. Current in Space Tony reports on a fascinating yet circumstantial finding that suggests a world literally on fire is out there, and it may excite fans of the Star Wars franchise. Then Amelia and Tony break down a study hinting at the existence of exoplanets that may be even more habitable than Earth! About Our Guest Sherry Suyu is a Max Planck Research Group Leader at the Max Planck Institute for Astrophysics, an Assistant Professor at the Technical University of Munich, and a Visiting Scholar at the Academia Sinica Institute of Astronomy and Astrophysics.

Episode 171: Ploonets: When Moons Go Rogue, with Jorge Zuluaga
Feature Guest: Jorge Zuluaga Astronomers have yet to confirm a single detection of an exomoon, that is a moon orbiting a planet outside our solar system. Now it turns out at least part of the explanation is that we may have been looking in the wrong place all this time. Introducing ploonets. No, I did not just mispronounce the word planet. Today we’re joined here at The Star Spot by Jorge Zuluaga, whose team coined the name to describe a moon that has gone rogue, and while it may sound exotic, a speculative theory posits that ploonets could have played a key role in the evolution of our very own planet. Current in Space Tony is back with an exciting discovery made in fresh snow in Antarctica: an isotope that can only have been manufactured in one place – the infernal heart of a supernova. Then Joseph and Tony once again ask the cosmic question: what are fast radio bursts, or FRBs, as eight more repeating FRBs have been detected in deep space, and we just may be on the cusp of solving the mystery. Finally, Amelia and Tony talk about a glitch. A software glitch? No. A neutron star glitch! About Our Guest Jorge Zuluaga is Professor of Astronomy at the Institute of Physics at the University of Antioquia in Colombia. His research interests include astrophysics, planetary science and astrobiology. He also enjoys teaching and popularizing Astronomy and Physics in his hometown.

Episode 170: The Mystery of Fast Radio Bursts, with Vikram Ravi
Feature Guest: Vikram Ravi They come to us from deep space. They last a tiny fraction of a second. They contain as much energy as the sun’s total output in 80 years. Yet we still haven’t figured out what causes these so-called Fast Radio Bursts or FRBs. I don’t want to say it’s aliens, but... no, it’s probably not aliens. Today we’re joined here at The Star Spot by Professor Vikram Ravi whose team is quickly zeroing in on the origin of these bizarre FRBs. Current in Space Amelia and Tony explain new research stating that worlds with completely frozen oceans, fittingly known as snowball planets, may actually be habitable . . . on the surface! And while the peak of the prolific Perseid meteor shower may have already passed, Simon reminds us that it's still not entirely over, and to get out there and take a look while you still can. Finally, robots are on the International Space Station! Joseph and Tony explain the purpose of three artificial helpers floating in the orbiting laboratory, one of which arrived only in late July. About Our Guest Vikram Ravi is Assistant Professor of Astronomy at the California Institute of Technology. He received a PhD from the University of Melbourne, then worked as the Millikan Fellow in Astronomy at Caltech followed by the Clay Fellow at the Center for Astrophysics at Harvard and Smithsonian.

Episode 169: Science at the Limits (Part 2)
Feature Guest: Dan Falk Scientists are finding themselves increasingly squeezed between academics sounding the limits of science and a public increasingly taken in by pseudoscience and conspiracy theories. Today we conclude our review of science under attack with science writer Dan Falk. Current in Space NASA is looking to make space exploration a little greener, and Joseph and Tony report on their latest invention: an environmentally-friendly spacecraft fuel that may eventually replace hydrazine, the toxic industry standard for decades. Then Simon terrifies us with the fact that mere days ago, an asteroid nearly hit Earth. Finally Amelia and Tony explain a strange feature found around lakes on Titan. About Our Guest Dan Falk is an award winning science journalist and broadcaster.

Episode 168: Celebrating Apollo + Science at the Limits (Part 1)
Feature Guest: Dan Falk Today we’re joined here at The Star Spot by science writer Dan Falk. We’ll start today’s interview with a commemoration of the 50th anniversary of the landing of humans on the moon and the internationalism of that critical moment. But then, 50 years after this triumph of science, we’re going to confront head on a set of old and new challenges to the scientific enterprise itself. All the fascinating research and discoveries we share at The Star Spot rests on basic assumptions about the primacy, scope and universality of science. In this two episode series, we take a step back and wrestle with some uncomfortable questions. What if the fundamental reality we probe is merely a simulation? Does science harbour blind spots that will forever limit its ability to build a theory of everything? And even if science is supreme, can it contend with conspiracy theories and pseudoscience - like the moon landing hoax belief - that undermine its legitimacy in the eyes of the wider public. Current in Space Tony explain a remarkable finding from the Curiosity rover on Mars: it's detected the biggest emission of methane on the red planet yet. Then Simon delves into the subject of a black hole so unusual that it shouldn't exist at all! And Amelia and Tony report on a new instrument that's being used to hunt for exoplanets in the Alpha Centauri system. About Our Guest Dan Falk is an award winning science journalist and broadcaster. He has been published very broadly, including Smithsonian, The Walrus, Cosmos magazine, Scientific American, NBCnews.com, Slate and New Scientist.

Episode 167: Current in Space + The Best of The Star Spot: Nobel laureate Brian Schmidt
Feature Guest: Brian Schmidt Today we offer a best of from our vault here at The Star Spot. We dug back to a fan favourite, our December 2014 interview with Nobel laureate Brian Schmidt, who won the biggest prize in science for discovering the accelerating universe. The 1929 discovery of the expanding universe by Edwin Hubble forever changed our picture of the cosmos and our understanding of our place in the universe. In 1998 we learned that wasn’t the only surprise. That’s when two teams of astronomers announced that the expansion of our universe isn’t slowing down as everyone assumed. Its speeding up. Today we’re joined at The Star Spot by Distinguished Professor Brian Schmidt who won the Nobel Prize for discovering our accelerating universe. Current in Space Tony and Amelia discuss a new finding from the ALMA observatory: a cool ring of gas encircling the supermassive black hole at the center of the Galaxy. Then Simon pulls you in with the measurement of a tiny black hole at the center of a nearby dwarf galaxy. And finally Tony returns with breaking news from the Jovian satellite system: Sodium chloride, aka table salt, has been found on none other than the ice-covered ocean moon Europa! About Our Guest Dr. Brian Schmidt is Distinguished Professor at the Australian National University Mount Stromlo Observatory and holder of an Australian Research Council Federation Fellowship. In 2011 Schmidt received the Nobel Prize in Physics for his co-discovery that the universe isn’t merely expanding, it’s actually accelerating in its expansion.

Episode 166: Nanodiamonds are Forever, with Jane Greaves
Feature Guest: Jane Greaves Remember that nursery rhyme, “Up above the world so high, like a diamond in the sky?” Well they were on to something, because it turns out diamonds - albeit nanodiamonds - are ubiquitous across the Milky Way galaxy. So-called diamond dust is even here in our own solar system. Today we’re joined at The Star Spot by Professor Jane Greaves, whose team made the discovery that unexpectedly solved a long standing astronomical mystery. Current in Space Simon explains a tantalizing find: 30 binary stars that have somehow been ejected from their home galaxies! Then Amelia and Tony report on a bizarre discovery: a star that's apparently the merger between two white dwarfs! About Our Guest Jane Greaves is Professor of Astronomer at Cardiff University in Wales. She is the recipient of the 2017 Fred Hoyle Medal from the Institute of Physics of London. In 2008 her team took the first direct image of a proto-brown dwarf candidate. Greaves uses textile art to communicate her passion for astrophysics with the public.

Episode 165: Landing on Europa, with Cynthia Phillips
Feature Guest: Cynthia Phillips In the 1970s, the Viking landers performed historic experiments aimed at detecting life in the Martian soil. The results were disappointing although to this day still not entirely conclusive. Now over 40 years later a new lander with a next generation set of life detection equipment is under assessment by NASA. This time the target is not the Red Planet, but the ocean moon Europa, which has emerged as a prime candidate in the search for life in the solar system. Today we’re joined here at The Star Spot by Cynthia Phillips, Deputy Project Scientist for the Europa Lander mission concept, who tantalizes us with dreams of flying through plumes and digging into an icy crust. Current in Space Tony goes into speculation mode and ponders the chances that interstellar interlopers, like the recent Oumuamua, could actually carry life and deposit it on planets, perhaps even Earth. Then Samantha debuts with a report on a new gravitational wave event, one which may be the result of a type of binary system merger we've been hoping for. Simon troubles us with the disturbing discovery of holes in the Milky Way that were punched by . . . something. And Amelia and Samantha talk the dazzling first-ever discovery of the so-called first-ever molecule in space. About Our Guest Cynthia Phillips is Planetary Geologist at the NASA Jet Propulsion Laboratory, a scientist with the SETI League and she also works at the Center for the Study of Life in the Universe.

Episode 164: Jupiter's Ancient Odyssey, with Simona Pirani
Feature Guest: Simona Pirani The planet Jupiter occupies a position today that is far from its home 4.5 billion years ago, a destination resulting from a primeval migration that started way out around the current location of Uranus. Like the god for which it was named, Jupiter enjoys the company of thousands of followers, the so-called trojan asteroids, which have remained by its side all these years, and they now offer a window into the murky origins of the gas giant. Today we’re joined here at The Star Spot by Simona Pirani, lead author of a new study that provides the first ever proof that Jupiter - and perhaps most planets - undertake ancient odysseys around the solar system. Current in Space We have bad news and good news. Simon puts a bit of a damper on things, as the first manned mission to Mars will have to wait longer than initially projected. Then Amelia and Samantha explain a crazy new finding: a pulsar that seems to be speeding through space! And we save the good news for last, as Tony shares new research suggesting that Earth-like planets orbiting red dwarf stars, which have been deduced as unlikely to host life, may actually be habitable after all. About Our Guest Simona Pirani is a doctoral student in the Department of Astronomy and Theoretical Physics at Lund University in Sweden. She is the lead author on a major new study into ancient planetary migrations.

Episode 163: The Ring Worlds of Saturn, with Bonnie Buratti
Feature Guest: Bonnie Buratti The spacecraft Cassini went out in spectacular fashion, travelling through Saturn’s rings for a final death dive into the gas giant. Even in its final heroic moments, Cassini was relaying back data shedding light on the bizarre worlds known as the ring moons of Saturn. The origin of these small bodies, which manage to maintain orbits within the turbulent environment of Saturn’s rings, pose a a puzzle for scientists. Today we’re joined here at The Star Spot by Bonnie Buratti of JPL with updates from her recently published study into this young and dynamic system of oddball worlds. Current in Space Dave presents a hole of a breakthrough: The much-anticipated Event Horizon Telescope has at last come online, and has already given us the stunning first-ever image of a black hole. Then Amelia and Samantha explore newly proposed possibilities concerning the habitable zone, the region around a star in which planets could support liquid water on their surfaces. And lastly Tony and Simon offer a back to back analysis of how we might save ourselves from a killer asteroid. Spoiler alert! The movies have it wrong, but we’re not entirely without hope. About Our Guest Bonnie Buratti is a planetary astronomer in the Division of Earth and Space Sciences at NASA's Jet Propulsion Laboratory, where she leads the Comets, Asteroids, and Satellites Group. She has worked on the Voyager program, the Cassini-Huygens spacecraft, the New Horizons space probe and the Rosetta mission.

Episode 162: The End is Nowhere Near Nigh, with Fred Adams
Feature Guest: Fred Adams If you thought the far distant future of our universe was going to be bleak, dreary and dark, well, you’d be right. But remember, the universe is still just a baby and it has many new experiences ahead of it. Over the many trillions of years of its unimaginably long life, new processes will take over, new forms of galactic structure will emerge and types of stars that have never existed will come to populate the galaxy. Today we’re joined here at The Star Spot by Fred Adams, not to mourn the death of the universe, but to celebrate its remarkable potential. The Astronomy and Space Exploration Society, a student group based at the University of Toronto, hosted its annual signature symposium event on Friday, February 15th, 2019. This year’s theme was “Boom to Bust,”with three keynote speakers covering, in turn, the birth, life and death of the cosmos. Once again The Star Spot was privileged to be on location to cover the event. And now we bring you the the conclusion of our special three episode series, featuring each fascinating speaker taking us from before the beginning into the unimaginably distant future of our universe. Current in Space Simon generates excitement following the recent historic unmanned test flight of SpaceX's Crew Dragon capsule, which shall pave the way for astronauts to once again launch into space from American soil. And it turns out we still have a lot to learn about white dwarf stars, as Amelia and Samantha bring you a tantalizing discovery: A white dwarf with an orbiting dust ring! Then we move out to the disk of the galaxy. Astronomers have had trouble measuring the mass of our galaxy, but as Tony explains, we may have finally figured it out thanks to a clever technique. About Our Guest Dr. Fred Adams is the Ta-You Wu Collegiate Professor of Physics at the University of Michigan. His recent work includes star formation in clusters, the development of a theory for the initial mass function for forming stars, and studies of extra-solar planetary systems.

Episode 161: The Boom Time of the Universe, with Rosemary Wyse
Feature Guest: Rosemary Wyse The universe is past its prime, by about 8 to 10 billion years. Sorry if you missed it. From the rate of star formation to the frequency of galactic mergers, the cosmos just isn’t what it used to be. Yet remarkably all is not lost, for there’s an astronomical archeology available to us. It turns out stars retain a memory of their ancient origins and galaxies hold clues to their own violent histories. Today we’re joined here at The Star Spot by Professor Rosemary Wise for the second in our three part series. Our coverage of the Symposium Boom to Bust: The Story of the Universe, continues with a Boom. The Astronomy and Space Exploration Society, a student group based at the University of Toronto, hosted its annual signature symposium event on Friday, February 15th, 2019.

Episode 148: Does Canada Have a Vision for Space Exploration?, with Chuck Black
Featured Guest: Chuck Black The Canadian Space Advisory Board was tasked with developing a plan to rejuvenate Canada’s declining world standing in space exploration. In 2017 the Board made a bold proposal that Canada designate space a national strategic asset and increase funding necessary for the “revitalization of Canada’s space capacity.” But when in March 2018 the federal government released its annual budget, these calls were entirely ignored. The chair of the Canadian Space Advisory Board was so disappointed that she took the unusual move of publicly critiquing a government which seemed to be neglecting Canada’s space sector. With little progress following years of industry consultation, where do we go from here? To help us understand how we got to this point and what can be done to reestablish Canada’s vision for space exploration, today we’re joined at The Star Spot by Chuck Black, the Editor of the Commercial Space Blog. Current in Space After the most extreme test yet of Einstein’s theory of General Relativity, Dave reports on the amazing results that will not surprise you in the least.

Episode 145: Can Sibling Rivalry Explain This Supernova?, with Stuart Ryder
Feature Guest: Stuart Ryder When a massive star explodes in a supernova, it tends to gobble up all the attention. But what happens when that star has a binary companion with its own story to tell? That’s exactly what happened last month when the Hubble Telescope captured the first image of the surviving stellar companion to a supernova, and it turned out to be more than just a passive observer. Today we’re joined at The Star Spot by the discovery team leader Stuart Ryder to tell us how sibling rivalry might account for the origin of one unusual type of supernova. Current in Space Tony details the launch of a new space telescope that will take planet hunting to the next stage. Then Maya shares a tantalizing discovery from Jupiter's largest moon.

Episode 144: A Rough Upbringing: The Discovery of Stars in the Galaxy’s Core, with Farhad Yusef-Zadeh
Feature Guest: Farhad Yusef-ZadehThe gravity, radiation and tidal forces at the very core of the Milky Way is kind of intense. That’s why astronomers have long doubted the possibility of star formation in such a hostile environment. And then everything changed with the discovery last fall of 11 sun-like stars living closer to the supermassive black hole at the centre of our galaxy then the distance between our sun and its closest neighbour. What does this breakthrough mean for our understanding of star formation and the possibility of life in what we once imagined were impossibly extreme environments? Today we’re joined here at The Star Spot by the discovery team’s leader Farhad Yusef-zadeh. Current in Space On behalf of The Star Spot, Tony says "Thank you, Stephen."

Episode 141: The Mysterious Origin of Superpowerful Radio Blasts, with Jason Hessels
Feature Guest: Jason Hessels The one thing we thought we knew about fast radio blasts was that these mysterious one-off phenomena must be associated with some of the most cataclysmic events in the universe. Then everything changed with last month’s announcement of the first ever detection of a source of repeating fast radio bursts. Today we’re joined at The Star Spot by co-discover Jason Hessels to rule on an important question: are scientists back to the drawing board or did they just achieve a breakthrough in our efforts to unlock this puzzle. Current in Space Europa is a tantalizing destination for exploration, but Dave worries that if we visit we might quickly find ourselves on thin ice.

Episode 135: Studying Cosmic Alchemy with Gravitational Waves, with Michael Landry
Feature Guest: Michael Landry The alchemists never did succeed in turning elements into gold and silver, and now we know why. It takes the merger of two neutron stars to produce these and other precious metals. That was the headline just two weeks ago when astronomers reported the first ever detection of gravitational waves from this so-called kilonova event. With this discovery we enter a new era. Today we’re joined here at The Star Spot by Dr. Michael Landry, head of the LIGO observatory at Hanford where this landmark discovery was made, to discuss the dawn of multi-messenger astronomy. Current in Space The original of high energy cosmic rays is still a mystery, but now Tony reports that the answer may be more far out - literally - than we imagined. Then Maya has an important lesson for us: don’t judge a book by its cover, or a planetary interior by its surface. And as we gaze up at the moon in our sky, Dave wonders if the moon once had skies of its own. About Our Guest Dr. Michael Landry is Detection Lead Scientist at the LIGO, the Laser Interferometer Gravitational-Wave Observatory, in Hanford, Washington. The LIGO observatories have been responsible for the first ever discoveries of gravitational waves, for which the Nobel prize in physics was recently awarded.

Episode 128: A Shocking Theory About the Multiverse, with Dan Falk
Feature Guest: Dan Falk What if everything we see in our universe is not all that there is. The concept of the multiverse has captured the imagination of both physicists and cosmologists, but for very different reasons. According to the many worlds interpretation of quantum mechanics, every quantum event triggers the creation of new parallel universes. Meanwhile many cosmologists studying the beginning of the universe have come to believe that inflation is an eternal process forever creating new universes. The quantum mechanical wave-function and cosmological inflation seem worlds apart. But what if these two dramatically different models were pointing to one and the same multiverse? In this second of our two part conversation, science reporter Dan Falk rejoins us here at The Star Spot to discuss this startling possibility. Current in Space Today Tony and Dave treat us to a special black hole double bill. First up, black holes were recently tested to determine if they really are every bit as exotic as we thought. And then, what happens to the supermassive black hole at the centres of merging galaxies? About Our Guest Dan Falk is an award winning science journalist and broadcaster.

Episode 111: Can Supernovae Cause Extinctions!?, with Shawn Bishop
Feature Guest: Shawn Bishop We’ve long known we’re made of star stuff, but now it turns out that life on Earth might be even more intimately connected to events in deep space than we imagined. Scientists recently reported the first ever discovery of supernova ash - atoms forged in the catastrophic explosion of dead stars - found buried in fossils created by bacteria right here on Earth. And most surprising of all these findings hint at a possible role for supernovae in bringing about mass extinctions, events which have changed the course of life on Earth and may do so again in our future. Today we’re joined at The Star Spot by the discovery team’s Professor Shawn Bishop. Current in Space We worry whether our search for extraterrestrial intelligence is looking in the right place. Tony tells us a better question might be whether we're looking at the right time. But might we be able to catch life ejected into space? Dave shares exciting evidence of enormous water jets coming from Jupiter's icy moon Europa.

Episode 110: Peering Into the Void, with Nico Hamaus
Feature Guest: Nico Hamaus Astronomers are no longer avoiding the void. Between the overdense zones of our universe, where most galaxies live, there exist vast regions of near emptiness that can stretch for hundreds of millions of light years. But these voids are not nearly as inconsequential as you might imagine and now they are finally getting the attention they deserve. Astronomers are peering into the void in the hopes of solving a variety of cosmic mysteries, from gleaning critical insights into dark matter to studying unique galaxies found in the voids. Today we’re joined at The Star Spot by Nico Hamaus as we study the spaces between. Current in Space Just as we're learning more about our solar system's own Kuiper Belt, we're also discovering that extrasolar systems may harbour similar structures. Dave helps us understand just where such disks may originate. And while it may be just a little world, Anuj tells us dwarf planet Pluto has a surprisingly complex inner (and surface) life.

The Star Spot Episode 104: The Great Terraforming Mars Debate: The Dream, with Chuck Black
Feature Guest: Chuck Black Ever consider moving to Mars? The Star Spot did. Along with the University of Toronto Astronomy and Space Exploration Society, we co-hosted a panel event exploring one of the most fascinating questions in which science meets science fiction. The great terraforming Mars debate. We were joined by a 5 member panel of experts, representing a wide range of backgrounds. We approached the issue from all angles: physics, astronomy, philosophy, ethics, commerce and politics. Now over the course of 4 episodes I’m being joined at The Star Spot by each of our guests from that event. We covered the science of Mars with planetary scientist Paul Delaney. We then turned questions of Martian and Earthling biology with Dr. Olathe MacIntyre. Finally, switching gears, we asked NASA’s planetary protection officer John Rummel if we should terraform a lifeless world. These have been weighty discussions so in this fourth and final interview with journalist Chuck Black of Canadian Aerospace News we’re going to have a little fun. We’re going to dream of our loftiest vision of a Martian colony and we’re going to ask, if we do opt for colonization, how would we choose who to send as ambassadors of our species. Current in Space About Our Guest Chuck Black is a journalist, technology advocate, public speaker and activist.

Even if we could make Mars habitable, we must confront the equally profound question, should we do it? If Mars already habours life, even just microbes, does that make terraforming off limits? If Mars has dormant life, should we reawaken it? And do humans have an imperative to spread life to the barren worlds of our solar system and beyond? To tackle these biggest of questions today we’re joined at The Star Spot by Professor John Rummel of NASA’s Planetary Protection Subcommittee. Current in Space What’s the best way to study the largest volcano in the solar system? Anuj explains.

Feature Guest: Olathe MacIntyre Ever consider moving to Mars? The Star Spot recently did. Along with the University of Toronto Astronomy and Space Exploration Society, we recently co-hosted a panel event exploring one of the most fascinating questions in which science meets science fiction. Can we terraform Mars to make it habitable? And if we can, should we? We were joined by a 5 member panel of experts, representing a wide range of backgrounds in order to approach the issue from all angles: physics, astronomy, philosophy, ethics, commerce and politics. Now over the course of 4 episodes we're joined at The Star Spot by each of our guests from that event. We started, appropriately, with the red planet itself. In our last episode planetary scientist Paul Delaney updated us with the most current understanding of the characteristics of Mars pertinent to the planet’s suitability for life. Today we look at the biology, turning the focus on us, that is, the biota of Earth. We’ll be asking what we need to change about Mars to make it friendlier to our kind of life? What techniques are available toward that end? And could Earth life itself play a key role in transforming the red planet? Current in Space Did you know dung beetles use the Milky Way galaxy for navigation. Don't believe us? Anuj will explain how it works.

Feature Guest: David Paige
There was once a time when scientists believed that beyond the Earth there lied a largely dry, barren and inhospitable solar system. But now we think there is likely to be liquid water below the surface of Jupiter’s moons Ganymede and Europa, a warm salty ocean below the crust of Saturn’s moon Enceladus and recently NASA confirmed that ancient lakes once flowed on Mars.
As the solar system wettens, are we witnessing a paradigm shift with profound implications in our search for life. To help us answer that question today we're joined at The Star Spot by the self-described “professional ice finder” David Paige.

Did you know human beings are not the only life forms aboard the ISS. Anuj explains. Then Tony builds on last episode's description of a Tatooine-like exoplanet by introducing another Star Wars fan favourite. It seems the Kepler space telescope has discovered an object that is been dubbed the "Death Star" for while it is no battle station it may be just as destructive to nearby planets.
About Our Guest

Episode 88: Two's Company: From Binary Stars to Binary Supermassive Black Holes, with Pawel Artymowicz
Feature Guest: Pawel Artymowicz
Star Wars fans will be familiar with the planet Tatooine and its two suns. But as it turns out the majority of stars in the Milky Way galaxy live with a companion. And that’s led scientists to study how multiple star systems form and develop, and whether they can host habitable planets.
To help us understand the behaviour of binary star system and the even more fascinating domain of supermassive binary black holes, the results of merging galaxies, today we're joined at The Star Spot by Pawel Artymowicz
Current in Space
Anuj shares new evidence that has pushed back the origin of life by hundreds of millions of years. Tony explains what measures scientists are using to predict the likelihood that newly discovered exoplanets are in fact habitable. Dave updates us on NASA's big water on Mars discovery with new analysis which is leading us to believe the red planet was much warmer and wetter than we had thought. And The Star Spot goes to the movies... off to Mars to be exact as Denise reviews The Martian.

Episode 87: 147 Years of Astronomy Outreach, with Randy Attwood
Feature Guest: Randy Attwood
Nearly a quarter of Americans confuse astronomy with astrology. And barely half know it takes the Earth a year to go around the Sun. Yes, you read that right. Clearly, we have a lot of work to do.
Today we're joined at The Star Spot by Randy Attwood. He’s Executive Director of the Royal Astronomical Society of Canada. RASC has been engaged in astronomy education for nearly 150 years. He joins me at a live recording of The Star Spot on location in Mississauga, Ontario, Canada.

Evidence for flowing liquid water on Mars has never been found...until now. Then Anuj updates our coverage of what appears to be the discovery of an infant solar system. Finally Tony surveys the worlds of our solar system where we now believe water to exist, in one form or another.
About Our Guest
Randy Attwood is Executive Director of the Royal Astronomical Society of Canada or RASC. He is the publisher of SkyNews, an astronomy periodical recently acquired by the society. Randy is a frequent guest commentator in the media, offering a thoughtful analysis of astronomy and space exploration news and events.

Episode 86: When the Universe Began, with Wendy Freedman
Feature Guest: Wendy Freedman
A long long time ago in every place at once, all of this began. But when exactly did the universe begin? And how quickly did it expand into the structure we see around us? Those numbers are more difficult to nail down than we had thought, yet more critical to our understanding of the nature of the cosmos, of dark matter and dark energy, than we could have ever imagined. Today we're joined at The Star Spot by cosmologist Wendy Freedman who recently stepped down after 12 years heading up the development of the Giant Magellan Telescope.
Current in Space
Anuj wonders if magnetic worm holes will one day transport us to the far reaches of space. And with Pluto data analysis just getting underway, Tony provides the new targets for the New Horizons spacecraft.
