We’re only two weeks away from starting our new season, with all new episodes, on September 17! We’re putting the finishing touches on the first episode as we speak, and we can’t wait to share it with you. But for now, enjoy one of our most favorite episodes about what everything in the universe is made of.

What are protons, neutrons, and electrons made out of? That’s what listener Xander wants to know. Physics expert Aatish Bhatia takes us on a journey into the atom, and explains how scientists discover things that are too small to see. You’ll find out how Albert Einstein helped prove the existence of atoms, and why physicists smash particles like pinatas in massive tunnels.

Learn more about this episode on the blog on our website.

How do scientists find out if an asteroid might hit our planet? And what do they do if it’s on a collision course with Earth? We’ll meet a planetary defender - an astronomer who uses radar telescopes to defend our planet from space rocks! Edgard Rivera Valentín grew up in Puerto Rico, next to Arecibo, the world’s most powerful radar telescope. Hear the story of how Edgard became a scientist superhero, and the supervillain asteroids they’re up against. 

A bonus interview episode with Edgard is available to Patreon members who pledge at the $1 level or higher at patreon.com/tumblepodcast. 

Check out more resources about Arecibo and asteroids on our blog, at sciencepodcastforkids.com.

Will An Asteroid Hit Earth?

How did cicadas evolve to go underground for so long? Why do cicadas spend so much of their lives underground? That’s what listeners Gus and Zachary want to know. This spring, up to a TRILLION cicadas will emerge across 16 states in the U.S., in an event that hasn’t happened since 1803. Cicada scientist Chris Simon helps us dig into the surprising science of cicadas - and figure out how they’re changing on this science podcast for kids.

Why Do Cicadas Live Underground for So Long?

Scientists stage an alien abduction to learn how bacteria avoid antibiotics, in this fact-meets-fiction episode! Meet our alien bacteria invaders (fiction) and our real life scientist, Caroline Blassick (fact) as they face off in a battle of microbial life and death. We’ll find out how Caroline implants mind-control devices in bacteria to improve human health, in bioengineer Mary Dunlop’s lab.
Our bacteria are played by Clara and Elijah, middle school STEM students. 
This episode is supported by the National Science Foundation under award number MCB 2032357.

The Alien Bacteria Abduction

Why can’t we see black holes? Can we see black holes with a telescope? That’s what Tumble listener James wants to know. We explore the science of supermassive black holes and gravitational waves, with the help of astronomer Maura McLaughlin. Find out how the LIGO telescope is aiding in the search for supermassive black holes on an intergalactic collision course!

ANNOUNCEMENT: Tumble en Español, the Spanish adaptation of Tumble, is back for Season 3! Listen here: https://www.sciencepodcastforkids.com/tumble-en-espanol
