  • A Podcast Turducken: With Wow in the World, Terrestrials and Circle Round
    Nov 17 2025

    Lulu is hosting a holiday meal. She’s invited the characters from her extended kids podcast family - Wow in the World and Circle Round - for an epic kids podcast crossover special. It’s a potluck of stories and on the table is a turducken. Yes, a turkey stuffed with a duck stuffed with a chicken. Each show brings a wild story about one of these creatures. We learn about a chicken’s unexpected journey back home, a duck mystery in the middle of the Arctic Ocean and an indigenous folktale about how the turkey got its gobble, culminating in a giant singalong.

    Keep learning!

    Check out Inge the chicken’s route back home.

    Read about the mysterious ocean quack sound.

    Learn about the turkey’s role in Cherokee culture.

    This episode was a huge collaboration between our team and the teams at Tinkercast’s Wow in the World and WBUR’s Circle Round, including Mindy Thomas, Guy Raz, Rebecca Sheir, Eric Shimelonis, Tom van Kalken, Steph Sosa and Anna Zagorski.

  • The Hybrid: A Miracle Mule
    Nov 13 2025
    In the game of life, every species is like an action figure. You got your dogs and your dung beetles, your bald eagles and your blueberries. And for a long time scientists believed it was pretty much impossible for those action figures to mix and make a new kind of action figure that was able to have its own babies (dog beetles? Baldberries? Nah). But, today we tell the story of a four-legged beast in Kentucky whose existence is upending scientific beliefs. If you want a big fat SPOILER, here it is: the creature in question is a mule! After almost 20 years of living her life as a hybrid (a mix between a horse and a donkey), believed to be incapable of having babies, Peanut the mule shocked the world by doing the impossible. Peanut’s owners, Teresa and Jerry Smothers, tell us the story of her life. Evolutionary biologist Dr. Molly Schumer explains how scientists’ understanding of hybrids has changed dramatically over the course of Peanut’s lifetime. And no mule episode would be complete without a cowboy-hatted mule packer leading us deep into the rocky trails of the American West on muleback to explain why mules are the best of both worlds of their parents.

  • The Night Flyer: How Bats sPOOkily Revive Forests
    Oct 30 2025

    This Halloween, we’re going to the dark side. Deep in the darkest tropical forests, some of the world’s most elusive bats hang upside down in their winged sleeping bags. On a quest to find one of these flying mammals, Producerbud Ana ventures into a Puerto Rican forest and the back corridors of the American Museum of Natural History with Dr. Angelo Soto-Centeno. Why? Because while they may be scary and look kinda like Dracula, with their sharp fangs and beady eyes, these bats hold something crucial for humanity - the ability to repair entire ecosystems after some of the most destructive hurricanes ever.

    But in this episode, we’re asking you to join us in setting our “ick” aside. If you stick with us, we promise that you’ll go from thinking these bugs are the grossest things ever to actually kinda liking them. Maybe even loving them.

    ER doctor Avir Mitra leads us down a rabbit hole of scientific discovery, explaining how these revolting critters have a history - and future - of saving human limbs and lives. Plus, a musical lesson in wound treatment 101.

  • The Travelers: How Moon Trees Hide Among Us
    Oct 2 2025

    In 1971, a red-headed, tree-loving astronaut named Stu ‘Smokey’ Roosa was asked to take something to the moon with him. Of all things, he chose to take a canister of 500 tree seeds. After orbiting the moon 34 times, the seeds made it back to Earth. NASA decided to plant the seeds all across the country and then… everyone forgot about them. Until one day, a third grader from Indiana stumbled on a tree with a strange plaque: "Moon Tree." This discovery set off a cascading search for all the trees that visited the moon across the United States. Science writer, and our very own factchecker, Natalie Middleton tells us the tale.

    We’re holding a Moon Tree contest! Send us a drawing of what you imagine a Moon Tree to look like. Submit here.

    If you happen to find a Moon Tree and visit it, email us pictures of you at terrestrials@wnyc.org! We’d love to feature you on our social media @terrestrialspodcast.

    Check out Natalie’s map to find your nearest Apollo 14 moon tree on our show page!

    Help us hunt for more moon trees. If you know of an undocumented moon tree, contact Natalie at nataliemiddleton.org. Check out Natalie’s essay on Moon Trees and Space Zinnias in Orion Magazine.

    Visit NASA’s official Moon Tree Page for a list of all the Apollo 14 Moon Trees in the world.

  • The Builders: How Beavers Mend Our Planet
    Sep 18 2025

    Few mammals have a bigger positive impact on the planet than the beaver. With its bright orange buck teeth, the creature is an expert engineer that brings life wherever it waddles and even fights fires. Our story begins in the Bronx river, once known as the “open sewer” of New York City. After some humans decide to clean it up, we meet one of the river’s residents - José the beaver. We learn about the US government parachuting beavers out of planes into the mountains. And finally head to California where we discover how one beaver family saved acres of land from burning.

    Special thanks to author Ben Goldfarb, Christian Murphy from the Bronx River Alliance and Dr. Emily Fairfax.

  • The Unimaginable: How Gravitational Waves (Literally) Rocked Our World
    Sep 11 2025
    Over a billion lightyears ago, in the darkness of outer space, a collision of black holes sent out a fleet of invisible waves that were headed right toward planet Earth. The waves were so powerful they could ripple spacetime but most people on Earth didn't believe the waves were real. SPOILER ALERT: The waves are called gravitational waves and…they are real! Astrophysicist Dr. Wanda Díaz Merced tells the story of what happened when they hit Earth in 2015 and how scientists came to learn to use senses beyond eyesight to detect the waves. We also learn from Dr. Stavros Katsanevas about the building of a giant gravitational wave catcher called “The Interferometer.” This episode also explores how to persist in the face of doubt as we learn Wanda's tale of going blind and learning how to listen to the stars. Learn about the storytellers, listen to music, and dig deeper into the stories you hear on Terrestrials with activities you can do at home or in the classroom on our website, Terrestrialspodcast.org. Watch the interferometer come to life, disco style, and find even MORE original Terrestrials fun on our Youtube.
