M57 - The Ring Nebula


The Ring Nebula, M57, is a glowing ring of gas that was thrown off by a dying star thousands of years ago. When viewed through a telescope M57 looks like a tiny white smoke ring. It is about 2,000 light-years away in the constellation Lyra. The dim barred-spiral galaxy to its upper right, IC 1296, is over 200 million light-years away.The image below shows some of the extremely dim, outer regions of the nebula.

For a description of the process that forms planetary nebulae, see the Dumbbell Nebula.
