Detailed Information:
The Crab Nebula was fisrt discovered by John Bevis in 1731 and observed by Messier on 12 September 1758. Chinese astronomers observed the supernova in 1054 A.D. The blast was so powerful and so close that it was visible as bright as Venus in the daytime sky for 23 days. It houses a rapidly spinning neutron star, a pulsar, which ejects material in a filamentous stream.
