The Crab Nebula shows the remains of an exploded star located about 6,500 light years from Earth. The powerhouse “engine” energizing the Crab system is a pulsar, a rapidly spinning neutron star, shooting out pulses of radiation 30 times a second. X-ray information from NASA’s Chandra X-ray Observatory was used to create a three-dimensional representation of the Crab. The X-ray structure shows the pulsar and a ringed disk of energized material, with jets of particles that fire off from opposite ends of the energetic pulsar.
