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 2021aefx was observed in multiband by the Precision Observations for Infant Supernovae Explosions (POISE) a day after discovery. The photometry was obtained on the 1 m Swope Telescope at the Las Campanas Observatory.
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 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.
Two people are fighting for life after an explosion at a chemical manufacturing plant in Louisville, Kentucky left 12 people in hospital.. The blast rocked Louisville’s Clifton Neighborhood on ...
The origins of such explosions are currently unclear, with events occurring at not more than 0.1% of the typical core-collapse supernova rate. [2] This class of transients initially emerged from large sky surveys at cosmological distances, [3] [4] yet in recent years a small number have been discovered in the local Universe, most notably AT ...
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.
The supernova peaked near apparent magnitude 12.1 on 19 June 2011. [8] Emission spectra indicated that the explosion was a type II supernova, in which a massive star collapses once nuclear fusion has ceased in its core. [4] SN2011dh was the third supernova to be recorded in the Whirlpool galaxy since 1994 (following SN 1994I and SN 2005cs). [10]
