The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. At the center of the nebula lies the Crab Pulsar, a neutron star 28–30 kilometers across with a spin rate of 30.2 times per second, which emits pulses of radiation from gamma rays to radio waves.
This photo was taken with Liverpool Telescope (Roque de los Muchachos Observatory) remotely during 120 seconds, with a H-Alpha filter on a IO CCD.
