Here is an image of the Ring Nebula (M57) a small planetary nebula in Lyra. When a star of average size dies, its core abruptly collapses while the outer layers are shed as an expanding shell of gases. This gas bubble can remain visible for centuries as a planetary nebula. The Ring Nebula, M57, is one of the finest examples.
