The word supernova has the plural form supernovae (/-v iː /) or supernovas and is often abbreviated as SN or SNe. It is derived from the Latin word nova, meaning ' new ', which refers to what appears to be a temporary new bright star. Adding the prefix "super-" distinguishes supernovae from ordinary novae, which are far less luminous.
A nova (pl. novae or novas) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star (hence the name "nova", Latin for "new") that slowly fades over weeks or months.
Type Ia supernova; Type Ib and Ic supernovae; Type II supernova; Superluminous supernova; Pair-instability supernova; Hypernova; 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
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.
The Type Ia supernova leaves no compact remnant, but the whole mass of the former white dwarf dissipates through space. The theory of this type of supernova is similar to that of novae, in which a white dwarf accretes matter more slowly and does not approach the Chandrasekhar limit. In the case of a nova, the infalling matter causes a hydrogen ...
It is from the title of this book that the modern word nova for cataclysmic variable stars is derived. [23] Multiwavelength X-ray image of the remnant of Kepler's Supernova, SN 1604. (Chandra X-ray Observatory) The most recent supernova to be seen in the Milky Way galaxy was SN 1604, which was observed on October 9
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 .
The Type Ib supernova SN 2008D [1] [2] in galaxy NGC 2770, shown in X-ray (left) and visible light (right), at the corresponding positions of the images. (NASA image.) [3]Type Ib and Type Ic supernovae are categories of supernovae that are caused by the stellar core collapse of massive stars.
