M1 Crab Nebula

Messier 1 (M1), also known as the Crab Nebula, Taurus A, or NGC 1952, is an expanding supernova remnant and pulsar wind nebula. It is located in the northern constellation Taurus, the Bull. The Crab Nebula has an apparent magnitude of 8.4 and can be seen with binoculars in good viewing conditions.

 

Messier 1 is the only supernova remnant listed in Messier’s catalogue and the most famous object of its kind in the night sky. The nebula has a total luminosity 75,000 times that of the Sun and lies at a distance of 6,500 light years from Earth.

 

The Crab Nebula is the result of a supernova explosion, SN 1054, that was observed by Chinese astronomers in 1054 AD. It was the first deep sky object to be associated with a historical supernova explosion.

 

Messier 1 is about 11 light years (3.4 parsecs) in diameter and keeps expanding at a rate of about 1,500 kilometres per second. The supernova remnant contains the Crab Pulsar, a rapidly rotating neutron star that spins at a rate of 30.2 times per second. The pulsar, also catalogued as PSR 0531+21, is the youngest one observed. It emits radiation in optical, radio, ultraviolet, X-ray and gamma ray wavelengths.
