The supernova remnant is called the Crab Pulsar. The collapsed core of the star is the Crab pulsar - a rapidly rotating neutron star. The Crab pulsar rotates 33 times a second, is 20 km in diameter, has a magnetic field one trillion times stronger than that of the Earth, and one pinhead of the pulsar would have the weight of a WWII battleship. The Crab pulsar is the youngest of 700 known pulsars and therefore the most energetic. Chandra will spend time looking at the Crab Pulsar as it is considered to be the Rosetta stone of astrophysics. View the Chandra X-ray image of the Crab Pulsar.
