Milky Way. Every star we see in the sky is part of the Milky Way, but a brighter center exists some light-years away. The Milky Way is about light-years in diameter and contains 200 to 400 billion stars.
Thought of this in my weird dream going into another galaxy underworld (pretty sure it was inspired by Stranger Things). I said in my dream a good idea for my birthday party could be a galaxy themed sleepover!
Remix Nebula - cloud of dust, hydrogen, helium and other gases that attract matter and materials to clump. These so called clumps form stars, planets, and other planetary systems. Nebulae are where the stars are formed!
