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.
The Webb images show tightly packed sheets, with filaments displaying structures on what NASA called "remarkably small scales," of about 400 astronomical units, or less than one-hundredth of a ...
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 ...
Since supernova neutrinos originate deep inside the stellar core, they are a relatively reliable messenger of the supernova mechanism. [3] Due to their weakly interacting nature, the neutrino signals from a galactic supernova can give information about the physical conditions at the center of core collapse, which would be otherwise inaccessible ...
