Jupiter's Moons
Before moving on from Jupiter to Saturn, we’re going to linger for a moment on Jupiter’s moons. There are 67 known moons, and 4 huge ones that we want to explore in greater detail. Ganymede is the largest - larger, in fact, than any...

The Great Escape
Do you know how many people have been to the moon? Only 12! Part of the reason it's so few is because of how difficult it is to escape Earth and get into space in the first place. In this episode of Crash Course Kids, Sabrina talks about...
