Crab Nebula

M 1 (Crab Nebula) is an expanding supernova remnant and pulsar in the constellation of Taurus. M1 is at a distance of 6500 light years and has a radius of 5.5 light years. M 1 was first recorded by Chinese astronomers as a “guest Star” in the year 1054 and was visible in the daytime sky for nearly a month.

At the heart of the Crab Nebula is an extremely dense neutron star spinning at an incredible 30 times a second, having the same mass as our sun but only a few kilometres across.
