Cygnus X is a big group of stars that are all hanging out together pretty close by each other. It's like a big family of stars! There are lots of different types of stars in this family, like big ones and small ones and hot ones and cool ones. They all live together in a big cloud of gas and dust, which is kind of like a cozy blanket they all cuddle up in. Sometimes, stars in Cygnus X might even make new baby stars in the cloud! It's a really neat and interesting place to study and explore for scientists who like to look up at the stars.
