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.
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 2018cow (ATLAS name: ATLAS18qqn; also known as Supernova 2018cow, AT 2018cow (AT = Astronomical Transient), and "The Cow") was a very powerful astronomical explosion, 10–100 times brighter than a normal supernova, spatially coincident with galaxy CGCG 137-068, approximately 200 million ly (60 million pc) distant in the Hercules constellation.
The supernova was also independently discovered by Kōichi Itagaki on 7 October 2013. [3] The star that produced SN 2013fs was a red supergiant with a mass 10 times the mass of the Sun, an effective temperature of 3,500 K, a radius 607 [4] times the size of the Sun, and no more than a few million years old when it exploded. [2]
SN 2022jli is a Type Ic supernova discovered in 2022 in the spiral galaxy NGC 157 at a distance of about 23 Mpc. The light curve of the supernova exhibited oscillations that are interpreted as an interaction of a companion star of the star that exploded with a compact object, probably a neutron star or a black hole. [2]
A super-luminous supernova (SLSN, plural super luminous supernovae or SLSNe) is a type of stellar explosion with a luminosity 10 or more times higher than that of standard supernovae. [1] Like supernovae , SLSNe seem to be produced by several mechanisms, which is readily revealed by their light-curves and spectra .
The SuperNova Early Warning System (SNEWS) is a network of neutrino detectors designed to give early warning to astronomers in the event of a supernova in the Milky Way, our home galaxy, or in a nearby galaxy such as the Large Magellanic Cloud or the Canis Major Dwarf Galaxy. As of March 2021, [1] SNEWS has
