We chew our food, swallow it, and our stomach goes to work on digesting! Our bodies absorb the nutrients they need and then we poop out the rest. Here on Earth, the whole process takes somewhere between one to three days. But what about in space? Do astronauts digest food as quickly as they do on Earth? We reached out to space scientist and science communicator Maggie Aderin-Pocock to get the answer!

A long time ago, in a galaxy far far away… we wondered, could you ever build a real lightsaber like the ones in Star Wars? A lightsaber is a glowing sword that can cut through metal – and pretty much anything else you can think of. It’s the favorite tool of heroes like Luke Skywalker and Ahsoka Tano, as well as villains like Darth Vader. That’s just in the movies, but could we make them real? We asked mechanical engineering professor Sayan Biswas to help us find the answer.

Did you know the tallest building in the world is a skyscraper in Dubai called the Burj Khalifa? It has 163 floors and weighs as much as 100,000 elephants! But how can the Earth even support such a huge building?! Why doesn’t the ground just collapse underneath it? We asked geologist Rónadh Cox to help us find the answer.

Some planets have lots of moons. Others have none. Earth has just one moon, but it’s a really great one. It can glow bright and white and sometimes it’s shaped like a big round ball. Other times it’s skinny like the white tip of a fingernail. Makes you wonder, why does the moon look the way it does? We asked Preston Dyches from NASA’s Jet Propulsion Laboratory to help us find the answer.

You fart. I fart. Your dog farts. We all fart! Or do we…? Birds don’t fart, and they’re the closest living descendants of the dinosaurs. So, did dinosaurs fart? We asked paleontologist Kallie Moore to help us find the answer.

Dinosaurs went extinct around 65 million years ago after an asteroid crashed into Earth. So we know when dinosaurs disappeared from the planet, but when did they appear? What was the first dinosaur, and how long ago did it live? We asked paleontologist Kallie Moore to help us find the answer.

Happy Dinosaur Week! Every episode this week explores the ancient marvels that walked the Earth millions of years ago. Fossilized bones and footprints help scientists figure out what these prehistoric creatures looked like – but how do we know what they sounded like? We asked paleontologist and science journalist Shaena Montanari to help us find the answer.
