The earliest recorded supernova was SN 185 observed by Chinese astronomers in 185 AD. The brightest recorded was SN 1006 described by Chinese and Arab astronomers. The widely observed SN 1054 produced the Crab Nebula. SN 1572 and SN 1604, observed in the Milky Way galaxy, were important because they were used to argue against the Aristotelian view that the universe beyond the planets was immutable. Telescopes have allowed observation of supernovae in other galaxies, such as SN 1885 in the Andromeda Galaxy. Supernovae provide important information on cosmological distances.
