Comment: |
M1, the Crab Nebula is remnant of the supernova that was observed by Chinese and Arab astronomers in year 1054. Reddish nebula filaments are remnants of the exploded star atmosphere. Bluish background is due to synchrotron radiation emitted by high speed electrons curving in strong magnetic field. Magnetic field is generated by pulsar, a rapidly rotating neutron star in the center of the nebula. The pulsar is a result of the supernova explosion. M1 is currently expanding at speed of 1500 km/s and accelerating due to the pulsar tremendous energy output. M1 distance is 6300 ly and its length is 11 ly. |
