 At the center of the crab nebula, a pulsar blasts out pulses of radiation thirty times a second. This Hubble image captures the region around the pulsar. It is centered on the region around the neutron star, the rightmost of the two bright stars near the center of the image, and the expanding filamentary debris surrounding it. The rightmost part of the shell is a blue glow that is radiation given off by electrons swirling at nearly the speed of light in the powerful magnetic field around the pulsar. Bright wisps are moving outward from the star at half the speed of light to form the expanding ring. It is thought that these wisps originate from a shockwave that turns the high speed wind from the pulsar into extremely energetic particles.
