Scientists use powerful telescopes to look at small patches of the sky and count the stars they can see. Then they use math to estimate how many stars are in the whole universe. The numbers are so big that they are hard to understand! Scientists think there might be around 200 billion trillion stars in the observable universe.
- There are more stars in the universe than grains of sand on all the beaches on Earth.
- You can only see about 2,500 stars with your eyes on a clear night.
