The Crab Nebula, also known as M1, NGC 1952, or Taurus A, is the remains of a supernova explosion and a pulsar wind nebula located in the Taurus constellation. Its name comes from a sketch made in 1842 or 1843 by William Parsons, the 3rd Earl of Rosse, who thought the shape resembled a crab. The nebula was first discovered in 1731 by English astronomer John Bevis. It matches up with a bright supernova observed by Chinese astronomers in 1054, marking it as the first astronomical object linked to a supernova recorded in history.
