The Crab Nebula is a supernova remnant that has an apparent magnitude of 8.4 and lies about 6,500 light-years away in the constellation Taurus. Corresponding to a bright supernova recorded by Arab, Chinese and Japanese astronomers in 1054, this nebula was observed by John Bevis in 1731 and was recorded as the first Messier object catalogued in 1758. Some catalogue designations for the Crab Nebula are M1 (Messier 1), NGC 1952, Taurus A, Sharpless 244 (Sh2-244) and LBN 833.
