But the supernova's appearance some 1,000 years ago has made it hard to analyse. In fact, the Crab was the first object in Messier's catalog, earning it the designation of Messier 1, or M1. It is expanding at a rate of 0.21 arcseconds per year. Usually a very dense core is left behind, along with an expanding cloud of hot gas called a nebula. It is, in a manner of speaking, still exploding today. The resulting remnant — the Crab Nebula — has been studied in great detail, and the supernova has been the best candidate for an electron-capture supernova.
