First spotted in the 18th Century and located around 2,500 light-years from Earth, the Ring Nebula’s colorful main ring is made up of gas thrown off by a dying star at the center of the nebula. This star will eventually become a white dwarf — a very small, dense, and hot core that marks the final evolutionary stage for a star, and one that our own sun will eventually follow. #space #spacenews #jameswebbspacetelescope
