List of supernovae. 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 ...
This is a list of supernova candidates, or stars that are believed to soon become supernovae. Type II supernova progenitors include stars with at least 8~10 solar masses that are in the final stages of their evolution. Prominent examples of stars in this mass range include Antares, Spica, [2] Gamma Velorum, [3] Mu Cephei, and members of the ...
Type Ib and Type Ic supernovae are categories of supernovae that are caused by the stellar core collapse of massive stars. These stars have shed or been stripped of their outer envelope of hydrogen, and, when compared to the spectrum of Type Ia supernovae, they lack the absorption line of silicon. Compared to Type Ib, Type Ic supernovae are ...
A hypernova is a very energetic supernova which is believed to result from an extreme core collapse scenario. In this case, a massive star (>30 solar masses) collapses to form a rotating black hole emitting twin astrophysical jets and surrounded by an accretion disk. It is a type of stellar explosion that ejects material with an unusually high ...
Which causes get the most money is determined by users. If it can capture 1% or more of the global social media advertising market, says Supernova, it would be passing £600 million a year to ...
Type Ia supernova. At the core of a planetary nebula, Henize 2-428, two white dwarf stars slightly under one solar mass each are expected to merge and create a Type Ia supernova destroying both in about 700 million years (artist's impression). A Type Ia supernova (read: "type one-A") is a type of supernova that occurs in binary systems (two ...
"Direct detection of pre-supernova activity in a red supergiant star has never been observed before in an ordinary Type II supernova. For the first time, we watched a red supergiant star explode!"
Steve is a player character from the 2011 sandbox video game Minecraft. Created by Swedish video game developer Markus "Notch" Persson and introduced in the 2009 Java-based version, Steve is the first of nine default player character skins available for players of contemporary versions of Minecraft. Steve lacks an official backstory as he is ...
