Astronomy Picture of the Day -- Rings Around the Ring Nebula

Explanation: It is a familiar sight to sky enthusiasts with even a small telescope. There is much more to the Ring Nebula (M57), however, than can be seen through a small telescope. The easily visible central ring is about one light-year across, but this remarkably deep exposure - a collaborative effort combining data from three different large telescopes - explores the looping filaments of glowing gas extending much farther from the nebula's central star. This remarkable composite image includes narrowband hydrogen image, visible light emission, and infrared light emission. Of course, in this well-studied example of a planetary nebula, the glowing material does not come from planets. Instead, the gaseous shroud represents outer layers expelled from a dying, sun-like star. The Ring Nebula is about 2,000 light-years away toward the musical constellation Lyra.

Such pics remind me of the groundbreaking theory (at the time) of Firestone that nova and supernova detonations were not nice, even, spherical distributions of expelled matter. Rather, the expanding shell of matter was “lumpy” and had denser areas than others.

Beautiful pic!
