SN 1054 is a supernova that was first observed on c. 10 July [O.S. c. 4 July] 1054, and remained visible until c. 12 April [O.S. c. 6 April] 1056. [ 2 ] α The event was recorded in contemporary Chinese astronomy , and references to it are also found in a later (13th-century) Japanese document and in a document from the Islamic world .
SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
In June 2021 a paper in the journal Nature Astronomy reported that the 2018 supernova SN 2018zd (in the galaxy NGC 2146, about 31 million light-years from Earth) appeared to be the first observation of an electron-capture supernova [67] [68] [69] The 1054 supernova explosion that created the Crab Nebula had been thought to be the best candidate ...
185 – Chinese astronomers become the first to record observations of a supernova, SN 185. 1006 – SN 1006, a magnitude −7.5 supernova in the constellation of Lupus, is observed throughout Asia, the Middle East, and Europe. 1054 – Astronomers in Asia and the Middle East observe SN 1054, the Crab Nebula supernova explosion.
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.

At its peak, the luminosity of SN 1054 may have been four times as bright as Venus, and it remained visible in daylight for 23 days and was visible in the night sky for 653 days. [16] [17] There are fewer records of supernova SN 1181, which occurred in the constellation Cassiopeia just over a century after SN 1054. It was noted by Chinese and ...
