SN 1054 remnant (Crab Nebula).. A supernova remnant (SNR) is the structure resulting from the explosion of a star in a supernova.The supernova remnant is bounded by an expanding shock wave, and consists of ejected material expanding from the explosion, and the interstellar material it sweeps up and shocks along the way.
This is a list of observed supernova remnants (SNRs) in the Milky Way, as well as galaxies nearby enough to resolve individual nebulae, such as the Large and Small Magellanic Clouds and the Andromeda Galaxy.
The remnant's age is still uncertain. There is some agreement that the progenitor supernova happened between 3,000 [3] and 30,000 [5] years ago. Recent Chandra [6] and XMM-Newton [7] observations identified a plerion nebula, close to the remnant southern rim. The point source near the apex of the nebula is a neutron star, relic of a SN
IRAS 00500+6713 is the catalogued infrared source for an unusual nebula in Cassiopeia, while the central star has a designation WD J005311, with the whole system designated as Pa 30. The central star and its surrounding shell were created by the supernova seen in the year 1181 ( SN 1181 ) as reported by Chinese and Japanese observers. [ 4 ]
W49B (also known as SNR G043.3-00.2 or 3C 398) is a nebula in Westerhout 49 (W49). The nebula is a supernova remnant, probably from a type Ib or Ic supernova that occurred around 1,000 years ago. It may have produced a gamma-ray burst and is thought to have left a black hole remnant.
It is a loose cluster approximately 10 million years old, within one of the Tarantula Nebula's superbubbles formed by the combined stellar winds of the cluster or by old supernovae. [ 1 ] NGC 2060 is often used synonymously for the supernova remnant N157B [ 2 ] (30 Doradus B [ 3 ] ) which is a larger area of faint nebulosity and strong radio ...
The remnant was also identified tentatively in the second Cambridge Catalogue of Radio Sources as object "2C 34", and more firmly as "3C 10" in the third Cambridge list. [15] There is no dispute that 3C 10 is the remnant of the supernova observed in 1572–1573.
CTB 1, also known as G116.9+00.1 and AJG 110, [1] nicknamed the Medulla Nebula, [2] is a supernova remnant located in the constellation Cassiopeia. It was discovered as a radio source in 1960 in a study of galactic radiation carried out at a frequency of 960 MHz.
