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.

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.

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.
This supernova, called Supernova 1987A, occurred 160,000 light years from Earth in the Large Magellanic Cloud, a dwarf galaxy neighboring our Milky Way. A light year is the distance light travels ...
