Boomerang Nebula Sticker
Boomerang Nebula Sticker
The Boomerang Nebula is what is called a protoplanetary nebula, which is a nebula that will soon be a planetary nebula. Despite their name, planetary nebulae have nothing to do with planets. Instead, they consist of ionized gas ejected from red giant stars late in their life. The Boomerang Nebula is particularly fascinating because it is the coldest place ever observed in the universe at a temperature of only 1 Kelvin!
