| Comment | The Crab Nebula is a supernova remnant in the constellation of Taurus. Corresponding to a bright supernova recorded by Chinese astronomers in 1054, the nebula was observed later by English astronomer John Bevis in 1731. The nebula was the first astronomical object identified with a historical supernova explosion. The nebula lies in the Perseus Arm of the Milky Way galaxy, at a distance of about 6500 ly from Earth. It has a diameter of 11 ly, and is expanding at a rate of about 1500 km/s. At the centre of the nebula lies the Crab Pulsar, a neutron star.(From Wikipedia) |
