SN 1987A was a type II supernova in the Large Magellanic Cloud, a dwarf satellite galaxy of the Milky Way. It occurred approximately 51.4 kiloparsecs (168,000 light-years ) from Earth and was the closest observed supernova since Kepler's Supernova in 1604.
It was the progenitor of supernova 1987A. The star was originally charted by the Romanian-American astronomer Nicholas Sanduleak in 1970, but was not well studied until identified as the star that exploded in the first naked eye supernova since the invention of the telescope, [1] when its maximum reached visual magnitude +2.8. [3]
The closest supernova observed since the invention of the telescope, [17] Supernova 1987A, occurred in the outskirts of the Tarantula Nebula. [18] There is a prominent supernova remnant enclosing the open cluster NGC 2060. Still, the remnants of many other supernovae are difficult to detect in the complex nebulosity. [19]
Ian Keith Shelton (born 30 March 1957) is a Canadian astronomer who discovered SN 1987A, the first modern supernova close and bright enough to be visible to the naked eye. Born in Winnipeg , Manitoba , Canada, Shelton received his B.Sc. in 1979 from the University of Manitoba and in 1981 began his professional career working as Resident ...

In 1987, it gained fame for detecting 8 of the roughly 10 58 neutrinos emitted by Supernova 1987A. This discovery was completely unexpected; supernovas as near as 1987a are extremely rare and virtually unpredictable. The detector collected data until 1991. [5] This volume of water contains on the order of 10 31 protons. In one year of ...

SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
