It was seen on Earth in the year 1054. At the center of the bright nebula is a rapidly spinning neutron star, or pulsar, that emits pulses of radiation 30 times a second. This view shows the Crab in the X-ray wavelength. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Xray-crab/Xray-crab.dc.xml Sun, 29 Aug 1999 12:00:00 GMT Infrared Crab Nebula. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/infrared-crab/infrared-crab.dc.xml The Crab Nebula, some 6,000 light years from Earth, is the remnant of a supernova explosion. It was seen on Earth in the year 1054. At the center of the bright nebula is a rapidly spinning neutron star, or pulsar, that emits pulses of radiation 30 times a second. This view shows the Crab in the infrared wavelength. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/infrared-crab/infrared-crab.dc.xml Thu, 01 Jan 1970 12:00:00 GMT Optical Crab Nebula. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/optical-crab/optical-crab.dc.xml The Crab Nebula, some 6,000 light years from Earth, is the remnant of a supernova explosion.
