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.
SN 1987A was caused by the explosion of Sanduleak -69 202. Observation data Epoch J2000 Equinox J2000 Constellation: Dorado: Right ascension: 05 h 35 m 27.92 s [1]
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.

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 ...
The classic example of a Type IIb supernova is SN 1993J, [41] [42] while another example is Cassiopeia A. [43] The IIb class was first introduced (as a theoretical concept) by Woosley et al. in 1987, [44] and the class was soon applied to SN 1987K [45] and SN 1993J. [46]
