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 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 ...
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.
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.
NASA's James Webb Space Telescope (JWST) has captured photos of one of the earliest supernovas ever seen, with features appearing like grains and knots found in a cut of wood. "Once upon a time ...
The SN 1987A neutrino data, although sparse, confirmed the salient features of the basic supernova model of gravitational collapse and associated neutrino emission. [19] It put strong constraints on neutrino properties such as charge and decay rate. [19] [20] The observation is considered a breakthrough in the field of supernova and neutrino ...
