The Ring Nebula, M57, is a planetary nebula located in the constellation of Lyra. It was discovered in 1779 by Charles Messier while he was searching for comets. It's doughnut like appearance is the result of gases being illuminated by the remnants of the central star which is now a hot white dwarf. The vibrant colors of the nebula are caused by different gases emitting light at different wavelengths. The reddish hue is due to hydrogen while the greenish blue is due to oxygen.
Located slightly above M57 in the image is the barred spiral galaxy IC1296. While M57 is about 2,300 lightyears away, IC1296 is far in the background at 238 million lightyears from earth. In 2013 a super nova (SN2013ev) was discovered in IC1296.
