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!
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!
