Ring Number Two

I posted a picture of the Ring Nebula or M57 a while ago, but it was not nearly as nice as I think this one is. Here you can see the different colors of the planetary nebula and even the white dwarf lying at the center. This planetary nebula was created when a red giant star expelled its outer layers of gas in its dying days, forming a shell of gas expanding away from the star.
