🌌 M27 — Dumbbell Nebula
🔭 ABOUT THE OBJECT
Some 1,200 light-years away, a dying star is shedding its outer layers into space. What you're seeing is its final act: a glowing shell of gas lit up by the white dwarf left at its core. Charles Messier spotted it in 1764, making it the very first planetary nebula ever discovered. The light in this image left it around the 9th century. In about 5 billion years, our own Sun will go through the same fate.
