An astronomer takes us on a tour of the universe to learn about the birth of stars and planets and how they get their spin.

While Earth's orbit is massive by human standards, other planets, particularly those closer to the sun, have made ...

It takes the Earth one year to orbit all the way around the sun. But the sun’s path around the Milky Way is much bigger. It ...

But because the moon's orbit is slightly tilted relative to Earth's orbit around the sun, it doesn't block out the sun on every orbit, hence why not every new moon results in a solar eclipse ...

Like Earth's orbit around the Sun, the moon's around Earth is elliptical, meaning oval-shaped. This means the space rock is positioned at various distances from the planet depending on the time of ...
