Supernova 1987A is the bright star at the centre of the image, near the Tarantula Nebula. 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.
Supernova 1987A – located in a neighbouring dwarf galaxy – has been observed for more than three decades Space telescope spies neutron star at core of famous supernova to solve three-decade ...
Supernova 1987A remnant near the center. In 1987, Supernova 1987A in the Large Magellanic Cloud was observed within hours of its light reaching the Earth. It was the first supernova to be detected through its neutrino emission and the first to be observed across every band of the electromagnetic spectrum. The relative proximity of this ...

With Supernova 1987A, the star's size and the neutrino burst's duration had suggested the remnant would be a neutron star, but this had not been confirmed through direct evidence.
February 23 – Supernova 1987a is observed, the first "naked-eye" supernova since 1604. Asteroid 7816 Hanoi is discovered by Masahiro Koishikawa . 10500 Nishi-koen is discovered.
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.

Sanduleak -69 202 (Sk -69 202, also known as GSC 09162-00821) was a magnitude 12 blue supergiant star, located on the outskirts of the Tarantula Nebula in the Large Magellanic Cloud. It was the progenitor of supernova 1987A .
