The Crab Nebula, Messier 1 (M1, NGC 1952), is the most famous and conspicuous supernova remnant, an expanding cloud of gas created in the explosion of a star (supernova) that was observed in the year 1054 AD. It shines as a nebula of magnitude 8.4 near the southern "horn" of Taurus, the Bull. It has apparent dimensions of 6 x 4 arc minutes and is about 6,400 light years away.
