Crab pulsar

[′krab ′pəl‚sär]
(astronomy)
A pulsar found in the center of the Crab Nebula with a period of about 0.033 second and that emits radiation at all wavelengths from the radio to the x-ray region.

These photographs include the pinpoints of stellar light making up the M13 globular cluster, Venus transiting across the face of the sun, the Horsehead nebula, the Crab pulsar, and the tentacles of the Tarantula nebula.
Among its most significant achievements to date are the discovery of a giant ring around the heart of the Crab Pulsar in the Crab Nebula -- the remains of a stellar explosion; the discovery of the first X-ray flare ever seen from a brown dwarf star; the resolution of the universe's high energy X-ray "glow" into millions of specific light sources; and the first unambiguous detection and X-ray measurement of emission lines associated with gamma ray bursts, mysterious blasts of high-energy radiation thought to be generated by the collapse of massive stars.
1 ( ANI ): A radio telescope that was once used to keep track of ballistic missiles has helped astronomers to find how the magnetic field structure and rotation of the young and rapidly rotating Crab pulsar evolves with time.
