NGC 1950
Discovered (Dec 23, 1834) by John Herschel
NGC 1951
Discovered (Dec 23, 1834) by John Herschel
NGC 1952 (= M1 = PGC 2817554 = PGC 2819678) = The Crab Nebula
Discovered (1731) by John Bevis
Recorded (Aug 21, 1758) by Charles Messier
An 8th-magnitude supernova remnant in Taurus (RA 05 34 32, Dec +22 00 52).The Crab Nebula is the remnant of the daylight supernova of 1054 AD. In the millennium since its formation, the nebula has expanded to a diameter of 10 light-years, with an average velocity of expansion of 1/2 % of the speed of light (about a thousand miles per second). The radiation of the nebula is caused by synchrotron radiation emitted by the millisecond pulsar at its center -- a neutron star rotating 30 times per second.
