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.

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]

Demi Moore and Rob Lowe were recently spotted together during a night out — and they might as well have time-traveled straight from the '80s.. The pair, who famously starred together in the 1986 ...
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.
