Definición
- An expanding cloud of debris from the explosion of a Type I supernova in the constellation Taurus. Its light reached Earth in 1054 and was visible to the naked eye even in the daytime. Lying about 6,300 light-years away, the Crab nebula is an intense radio source (Tau A), and also a source of X-rays and gamma-rays. The diameter of the supernova remnant is about 6 light-years; it is expanding at velocity of 1000 km/sec. (An Etymological Dictionary of Astronomy and Astrophysics, by M.
