1054 - A supernova is observed by the Chinese and Amerindians near the star Tauri. For several months it remains bright enough to be seen during the day. Its remnants form the Crab Nebula.
The Crab Nebula (catalogue designations M1, NGC 1952) is a supernova remnant in the constellation of Taurus. The nebula was first observed in 1731 by John Bevis. It is the remnant of a supernova that was recorded by Chinese and Arab astronomers in 1054. Located at a distance of about 6,300 light years (1.93 kpc) from Earth, the supernova actually occurred around 5250 B.C.E. (in time measured with the rest frame of the Earth). The nebula has a diameter of 6 light years (1.84 pc) and is expanding at a rate of about 1,500 kilometers per second.
