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.
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 ...

Neutrinos, tiny sub-atomic particles, were produced in Supernova 1987A and detected on Earth 37 years ago, the day before the supernova was seen, indicating a neutron star must have formed.
Images revealed previously unseen crescent-like structures in the SN 1987A supernova and its remnant 168,000 light years from Earth, thought to be part of the outer layers of gas from the ...
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.

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.
