⭐

Did you know?There are more galaxies in the universe than there are grains of sand on all the beaches on Earth.

What is the Milky Way? Revealexpand_more

The Milky Way is the name of our own galaxy, the huge swirl of stars that our Sun lives in. On a very dark night, far from city lights, you can see part of it as a pale, milky band stretched across the sky.

🌟

Talk about itWhy do you think we can see many more stars away from city lights?

⭐

Did you know?That milky band is really the light of countless stars, too far away to tell one from another.

🎲

How many stars are there? Revealexpand_more

There are far too many stars to count, more than anyone could ever say out loud in a whole lifetime. Our galaxy alone holds hundreds of billions, and there are billions of other galaxies, each packed with stars of its own.

🌟

Talk about itWhat is the biggest number you can think of?

⭐

Did you know?If you counted one star every second, you would need thousands of years just for our own galaxy.

🎲

Try itCount to one hundred, then imagine that number stacked as tall as a mountain. That is still tiny next to the number of stars.

Could there be another planet like Earth? Revealexpand_more

🌟

Talk about itIf you could send one message to another planet, what would you say?

⭐

Did you know?Planets around other stars are called exoplanets, and new ones are discovered almost every week.

🎲

Try itLook up at the night sky and pick a star. Imagine a planet circling it, maybe with someone looking back at you.
