Apparent supraluminal motion in this object was recently resolved by radiation hydrodynamical considerations, in light of the thirty-three-microsecond source at its center. It was determined in 1973 to be six thousand, three hundred light-years away, which gives it an apparent magnitude of negative three point two. About ten light-years in diameter, it was misclassified in
Apparent supraluminal motion in this object was recently resolved by radiation hydrodynamical considerations, in light of the thirty-three-microsecond source at its center. It was determined in 1973 to be six thousand, three hundred light-years away, which gives it an apparent magnitude of negative three point two. About ten light-years in diameter, it was misclassified in 1919 and William Herschel originally thought it was a stellar system that could be resolved with larger telescopes. The inner part of this body appears bluish and emits synchrotron radiation. It also contains NP0532, a pulsar, and an x-ray source, Taurus X-1. FTP, identify this body independently discovered by Bevis and Messier; the nebula resulting from the 1054 supernova, designated M1.
