Westerhout 40

Westerhout 40 is a group of stars that are all together in space. It's kind of like a family of stars that live in the same neighborhood. Scientists call it a star cluster because all these stars are clustered or grouped closely together.

Just like we have different types of families, stars also come in different sizes and colors. Westerhout 40 has a lot of different stars, some are big and bright, others are small and dim.

Scientists like to study Westerhout 40 because it can teach us a lot about how stars form and grow over time. They can use special instruments to look at the light that the stars give off and see if they're moving closer or farther away from us.

Overall, Westerhout 40 is a really interesting group of stars that astronomers study to learn more about how the universe works!
