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 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 ...
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 ...
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 ...
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.
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 .
Neutrinos generated by a supernova were observed in the case of Supernova 1987A, leading astrophysicists to conclude that the core collapse picture is basically correct. The water-based Kamiokande II and IMB instruments detected antineutrinos of thermal origin, [ 14 ] while the gallium -71-based Baksan instrument detected neutrinos ( lepton ...
