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.
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.
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 ...
SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
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.
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 ...
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. [5] This volume of water contains on the order of 10 31 protons. In one year of ...
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.
