A supernova (pl.: supernovae or supernovas) is a powerful and luminous explosion of a star. ... The star is located in a spiral galaxy named NGC 7610, ...
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.
The supernova was about 21 million light-years from Earth and is expected to have left behind either a neutron star or black hole, based on current stellar evolution models. The supernova is located near a prominent HII region, NGC 5461, in an outer spiral arm of the bright galaxy. [3] By 22 May 2023, SN 2023ixf had brightened to about ...
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (less than roughly 10 to 300 parsecs [33 to 978 light-years] away [2]) to have noticeable effects on Earth's biosphere.
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.
SN 1006 was a supernova that is likely the brightest observed stellar event in recorded history, reaching an estimated −7.5 visual magnitude, [3] and exceeding roughly sixteen times the brightness of Venus.
This background image of the region around supernova remnant Cassiopeia A was released by NASA’s Spitzer Space Telescope in 2008. By taking multiple images of this region over three years with ...
The supernova is located in the galaxy PLCK G165.7+67.0 Arc 1 (Arc 1 for short) located at redshift z=1.78, behind the lensing cluster PLCK G165.7+67.0 (G165 for short) located at redshift z=0.35, and is triply imaged, each image called Arc 1a, Arc 1b, Arc 1c. This galaxy is part of a compact group of galaxies, of 6 members, 4 of which surround ...
