EDUCATION RESOURCES: NGSS Standards: ESS What if there was no moon? In this episode, we find out that there's a lot of fascinating lunar science that goes into answering that question. Miquel Sureda is a Spanish astrophysicist and science communicator who helped us figure it out. Check out his Spanish language blog, Gaia Ciencia. And before we get to the science, one more thing: We collaborated with fellow Kids Listen podcast What If World to tell a much less science-based s

EDUCATION RESOURCES: NGSS Standards: ESS In this episode, our listener Ilan shares his brilliant plan to stop climate change in its tracks, and make Mars a place we can live. He wants to filter Earth's excess carbon dioxide from our atmosphere, and then ship our carbon dioxide to Mars to thicken its atmosphere. But will it work? What does it take to get a scientific idea off the ground? Fortunately, there's a road map to blasting off to Mars with a payload of CO2! It's called

Do solar systems move or do they just stay there? Listener Levan had this question. In this episode, we learn that our solar system - and all others - are moving through space in many different ways. EDUCATION RESOURCES: NGSS Standards: ESS Technology plays a huge role in what is possible to learn about our solar system. When our ancestors looked up at the sky on a starry night, they couldn't comprehend how our planet is physically moving through space. But with the invention

It's one of the oldest questions that humans ask about our place in the universe: Are we alone? Or are there other intelligent beings out there, somewhere, in space? EDUCATION RESOURCES: NGSS Standards: LS We've been looking for the answer for a long time. There's even a term for it: SETI. That's short for Search for ExtraTerrestrial Life. SETI has been going on since we first gained the ability to look into the night sky with telescopes, over a hundred ago. But those teles

EDUCATION RESOURCES: NGSS Standards: ESS What do you need to make the cut to be an astronaut bound for Mars? The process to be chosen for a mission - whether on Earth or in space - is very intense. A lot of people want to go to Mars! CLICK HERE TO SEE THE APPLICATION FOR MARS ONE, A PRIVATE COMPANY THAT WOULD LIKE TO BE THE FIRST TO SETTLE MARS. Here's Mars One's "Five Key Characteristics of An Astronaut." Do you fit the bill? Applications for Mars One closed in 2013. But H

How do black holes work? And how do we learn about them, when they're impossible to see? EDUCATION RESOURCES: NGSS Standards: ESS Karl Gebhardt is one of the world's top experts when it comes to black holes. He's a professor of astrophysics at the University of Texas. In his career, he's helped find half of the 80 known black holes in the universe. One of them was the biggest black hole known in the universe - 17 billion times heavier than the sun! Dr. Gebhardt is now worki

In this episode, we take you inside the famed Explorers Club in New York City, where we meet a real explorer! Richard Garriott de Cayeux has been around the world and into space on scientific expeditions. He shares the stories of famous explorers and his own family expeditions – beginning with his astronaut dad. Plus, he explains on how to find a real meteorite near your house! Tales of wild exploration have you wanting more? Fear not! We've got you. Tour The Explorers Club!

Does the universe go on forever? Or does it have an edge? Jack and Kate have a few ideas about how to find out, involving a GoPro and a rocket. We ask astrophysicist Katie Mack if the universe is infinite and if a robot explorer will ever send us a selfie from the very edge of its expansion. Her answer will boggle your mind.

EDUCATION RESOURCES: NGSS Standards: ESS 5-ESS1-1 Dark Energy. The name sounds like something out of science fiction, and so does the description: A mysterious force that's pulling the universe apart. It was discovered in 1998 by two separate teams of astronomers who were competing to solve a simpler problem. They wanted to know the rate at which gravity is slowing down the universe's expansion. But what they found surprised everyone. The universe's expansion is not slowing d
