The Crab Nebula (M1, NGC 1952 or Taurus A) is the remnant of SN 1054, a pulsar wind nebula, about 6,000 light-years away in the Taurus constellation. It has a diameter of 11 light-years and is part of the Perseus Arm of the Milky Way.
The 958-year-old neutron star in the Crab Nebula is one of the best known pulsars. It rotates around its own axis 33 times every second and has a magnetic field of 100 million Tesla, over a trillion times stronger than that of Earth. The pulsar powers the surrounding famous Crab Nebula.
