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.
Boom.In the colossal Pinwheel galaxy, 25 million light-years away, a star has just exploded and is even visible through small telescopes. The supernova-hunting astronomer Koichi Itagaki discovered ...
SN 2016aps (also known as PS16aqy and AT2016aps) is the brightest and most energetic supernova explosion ever recorded. [2] [3] It released more energy than ASASSN-15lh. [4]In addition to the sheer amount of energy released, an unusually large amount of the energy was released in the form of radiation, probably due to the interaction of the supernova ejecta and a previously lost gas shell.
N103B (also known as SNR 0509–68.7) is a supernova remnant located in the Large Magellanic Cloud. [1] It is relatively close to Earth, allowing astronomers to observe and study the remnant. It lies a short distance from NGC 1850 .
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 ...
Astronomers have found evidence that a neutron star exists at the centre of the only exploding star – supernova – visible to the naked eye in the last 400 years, solving a 30-year-old mystery.
Supernova remnants driving a shock through the interstellar medium (ISM). Shocks traveling through a massive star as it explodes in a core collapse supernova. [4] Shocks in interstellar gas, caused by a collision between molecular clouds or by a gravitational collapse of a cloud. Accretion shocks at the edge of galaxy clusters.
