Solar System

Humans have visited the moon but we’ve never lived there. Could we build a home on our lunar neighbor?

Satellites are like robots in the sky: they monitor the weather, make GPS possible, and take stunning pictures of outer space! But how exactly do they work?

Explore the dark with Molly and co-host Sasha!

Pluto is tiny, icy, and used to be the ninth planet in the solar system. Used to be. So why isn’t Pluto a planet anymore?

Everything in our world is powered by energy!

What would life look like in other parts of the galaxy, or beyond?

We’ll unpack one of the most important ideas in science, the Theory of General Relativity!

We’ve got five space-inspired games for you: Cosmic Couplets, Infini-Trivia, First Things First, Stars in Space or Pasta Shapes and, of course, Mystery Sounds!

Find out where tardigrades live, what they eat and why we sent them to space!

Living on Earth, it’s hard to imagine there are bits of stars in us, but it’s true!

Get ready to learn the science behind the multiverse! That’s the idea that our universe isn’t the only universe out there. What if there were other, different universes existing alongside our own? Ones with different laws of physics, different planets and stars… or maybe even different versions of us!

In this episode we explain a few different theories behind this popular idea.

We’re heading to space, and dropping a feather in a few different places to see what happens!

How are mountains made? What causes an earthquake? How does hot lava come bubbling up? The answer in each case is…tectonic plates!

Listen to hear how the origins of our solar system involve a kind of cosmic pancake. And, how the Milky Way plays an important role in cultures all over the world.

Like an onion, the Earth has layers. In this episode we’ll see if you can dig through those layers to get to the center of the planet. We’ll also hear about the Danish scientist who discovered more about Earth’s core by studying earthquakes. Children’s book author and illustrator Oliver Jeffers stops by to talk about the Earth’s top layer called the crust.

Get ready for some smiles! We’re looking at the science of two things that bring us joy: tickles and cuteness. We’ll explain why tickles make us giggle and why you can’t tickle yourself. Then we’ll talk about what makes cute things cute and why sometimes we want to eat or smoosh cute things. Plus, a super cute Mystery Sound and a Moment of Um answering the question: “Can a moon have a moon?”

We don’t usually think about dust unless we’re cleaning up, but it’s all around us all the time. There’s more to this stuff than just boring, old grey specks. Way more.
