For centuries, the Northwest Passage, the long-sought sea route connecting the Atlantic and Pacific Oceans through northern Canada, was a holy grail of Arctic exploration. Even now, sailing through it isn’t guaranteed. Mark Synnott, a National Geographic Explorer, writer, and adventurer, attempted to sail his own boat through the Northwest Passage to retrace the doomed 1845 expedition of British explorer Sir John Franklin. None of the Franklin expedition’s 129 men made it home, but what exactly happened remains a mystery.   For more information on this episode, visit natgeo.com/overheard. Want more?

For decades, the U.S. government evangelized fire suppression, most famously through Smokey Bear’s wildfire prevention campaign. But as climate change continues to exacerbate wildfire seasons and a growing body of scientific research supports using fire to fight fire, Indigenous groups in the Klamath Basin are reviving cultural burning practices that effectively controlled forest fires for centuries. In an episode originally published June 2022, National Geographic photographer Kiliii Yüyan introduces us to people bringing back this cultural practice and teaching the next generation how to use fire.

National Geographic Explorer Tara Roberts is inspired by the stories of the Clotilda, a ship that illegally arrived in Mobile, Alabama, in 1860, and of Africatown, created by those on the vessel—a community that still exists today. The archaeologists and divers leading the search for the Clotilda lay out the steps it took to find it. In this last episode of the Into the Depths podcast, which published in March 2022, Tara talks to the living descendants of those aboard the ship. She admires their enormous pride in knowing their ancestry, and wonders if she can trace her own ancestors back to a ship. She hires a genealogist and visits her family’s small hometown in North Carolina. The surprising results bring a sense of belonging to a place that she never could have imagined. Want more?

Are we alone in the universe? It’s a question we’ve been asking for millennia. Now we’re on the cusp of learning the answer. Frank Drake—one of the most vocal (and brilliant) askers—has spent the past six decades inspiring others to join him in this quest. Now, a new generation of scientists is carrying his work forward. They’re finally being taken seriously, and they’re about to change the way we think about our place in the cosmos. For more information on this episode, visit natgeo.com/overheard. Want more? Space isn’t the only place to explore when scientists are looking for alien life; it’s also important to go underground—here on Earth. Find out why on another episode of Overheard. Breakthrough Listen is reaching beyond our galaxy to determine whether or not there is life in space. The project is audacious—and worth following closely. Frank Drake and Carl Sagan had a legendary friendship and professional relationship. One of their many projects was to create another kind of cosmic road map meant to show aliens how to find us.  Also explore: In 1977, NASA sent a set of Golden Records to space attached to two Voyager spacecraft. Carl Sagan, Frank Drake, and a team of inspired scientists decided what they should contain. Here’s the music that’s flying outside of our solar system right now. Thanks to another kind of map, it’s possible to see just how far those radio signals have traveled since leaving our planet over a hundred years ago. So far, they’ve traveled about 200 light-years—and no one has heard them yet. If you like what you hear and want to support more content like this, please consider a National Geographic subscription.

There is still a church on that site, aptly named Domine Quo Vadis, for the famous phrase St. Peter uttered before he returned to Rome and was crucified himself. You can see Annibale Carracci’s 17th-century painting of the event here. If going underground and being surrounded by bones doesn’t give you the willies, then you’ll love visiting the catacombs in Italy.

Social media is not just for modern folk. In this episode from the Overheard archives, we’ll look at how in ancient Pompeii, people also shared what they thought, who they met with, what they ate—just with different technology. For more information on this episode, visit nationalgeographic.com/overheard Want more? The new book Lost Cities, Ancient Tombs: A History of the World in 100 Discoveries details the story of Pompeii and other milestones in the human journey. Pompeii is not just an archaeological site; it's one huge graveyard. But it was very much a living city right up until it was snuffed out by Mt. Vesuvius. When you think of an avalanche, you probably think of snow. But volcanoes also cause avalanches. Archaeologists believe that it was an avalanche of rocketing, boiling gas and sediment that cooked Pompeiians alive in 79 A.D. In the late 1800s, archaeologists started pouring plaster into voids left in the hardened volcanic ash covering Pompeii. The result? Full-sized casts of Vesuvius' victims—human and otherwise. Do you live in the shadow of a volcano? Here are a few safety tips for when that telltale rumbling begins. Could Chernobyl be our contemporary version of Pompeii? Some archaeologists think so. Also explore: Curious about how Pompeii's graffiti compares to the stuff in your own backyard? Check out images of ancient Pompeiian graffiti at the Ancient Graffiti Project.

How did the planets form? How did life happen? Where did Earth’s water come from? To answer questions like these, scientists used to go big—looking at planets, dwarf planets, and moons—but now small is the new big. Technology is zooming in on the pint-size stuff—asteroids, comets, meteors, and other chunks of space rock—that couldn’t be studied before, and Lucy, a spacecraft designed to visit eight asteroids near Jupiter, is poised to learn how the secrets inside these small bodies are reshaping ideas about the big old solar system.

Social Media is not just for modern folk. In ancient Pompeii, people also shared what they thought, who they met with, what they ate... It's just, they had to use different technology. For more information on this episode, visit nationalgeographic.com/overheard Want more? Pompeii is not just an archaeological site, it's one huge graveyard. But it was very much a living city right up until it was snuffed out by Mt. Vesuvius. When you think of an avalanche, you probably think of snow. But volcanoes also cause avalanches. Archaeologists believe that it was an avalanche of rocketing, boiling gas and sediment that cooked Pompeiians alive in 79 A.D. In the late 1800s, archaeologists started pouring plaster into voids left in the hardened volcanic ash covering Pompeii. The result? Full-sized casts of Vesuvius' victims -- human and otherwise.
