Supernova remnant Messier 1. It is the result of a massive star that exploded and was observed on Earth in 1054 AD. The pulsar at the center of the nebula rotates about 30 times each second. The image spans about 10 light-years across. [3864 x 3864] (Credit: NASA/ESA, J. Hester and A. Loll) via /r/spaceporn
