The '''Crab Nebula''', also know as '''M1''' and '''NGC 1952''', is an expanding gas cloud surrounding a [[neutron star]] located in the constellation of [[Taurus]] near the star [[Zeta Tauri]], the south horn of the bull. Possibly the most famous [[nebula]], it is the result of a [[supernova]] event that was first observed on [[Earth]] in 1054 A.D.  Since then, the nebula has been expanding at a rate of 1500 km/s and is now on average some 11 light years in diameter.
