NASA artist's impression of the explosion of SN 2006gy, a superluminous supernova. 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]
It is a type of stellar explosion that ejects material with an unusually high kinetic energy, an order of magnitude higher than most supernovae, with a luminosity at least 10 times greater. Hypernovae release such intense gamma rays that they often appear similar to a type Ic supernova , but with unusually broad spectral lines indicating an ...
Supernova impostor, stellar explosions that appear similar to supernova, but do not destroy their progenitor stars Failed supernova; Luminous red nova, an explosion thought to be caused by stellar collision; Solar flares are a minor type of stellar explosion [1] Tidal disruption event, the pulling apart of a star by tidal forces
The explosion should be visible to the unaided eye for several days and just over a week with binoculars before it dims again. Keep an eye out online for reports that the explosion has occurred.
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.
Quark-nova – Hypothetical violent explosion resulting from conversion of a neutron star to a quark star; Superluminous supernova – Supernova at least ten times more luminous than a standard supernova; Supernovae in fiction; Timeline of white dwarfs, neutron stars, and supernovae – Chronological list of developments in knowledge and records
Also, rather than cooling down with time as expected of a Type II-P supernova, the object maintains a near-constant temperature of about 5000–6000 K. [1] Checks of photographs from the past found one from 1954 showing an explosion in the same location. [4] Since 1954, the star has exploded six times. [9] The principal investigator [10] is ...
The remnants of the giant stellar explosion can still be seen today. This image combines data from the Spitzer Space Telescope , Hubble Space Telescope and Chandra X-ray Observatory. Credit: NASA
