Hey kiddo, do you know that our galaxy, the Milky Way, is just one of many galaxies in our universe? In fact, there are trillions of galaxies out there, each containing billions of stars like our sun.
Now, imagine all of these galaxies grouped together in a huge cluster. This cluster is so enormous that it's called a supercluster! It's made up of many smaller clusters of galaxies that are all connected together by gravity.
Think of a supercluster as a giant city made up of smaller neighborhoods. Each neighborhood has its own houses and families, but they all come together to form one big city.
Superclusters are some of the largest structures in our universe and can be up to hundreds of millions of light-years across! That's really far away, even way beyond what we can see with our telescopes.
Scientists are still studying superclusters to learn more about how they form and evolve over time. It's a fascinating topic and one that continues to amaze and awe us.
