Image of the Day: Monster at the Center of the Crab Nebula

Crab
 

The Crab Nebula is a pulsar wind nebula and a supernova remnant that was recorded by Chinese astronomers and Arab astronomers in 1054 AD with a luminosity about 75,000 times greater than that of the Sun in the constellation of Taurus. At the center of the nebula lurks the Crab Pulsar, a rotating neutron star, which emits pulses of radiation from gamma rays to radio waves with a spin rate of 30.2 times per second. The discovery of a pulsating radio source in the centre of the Crab Nebula was strong evidence that pulsars were formed by supernova explosions.
