Crab nebula (M1), radio telescope image. This nebula is the remnant of a supernova that lies 6, 500 light-years from Earth. At its centre is the remains of the star's core, which has formed a pulsar, or neutron star, that rotates 30 times a seconds and emits regular pulses of radiation. The nebula's shape is caused by a complex interplay of the pulsar, a fast-moving wind of particles coming from the pulsar, and material originally ejected by the supernova explosion and by the star itself before the explosion. This image was obtained by the Very Large Array (VLA) in November 2012. | |
