The Sun is predicted to experience a flash 1.2 billion years after it leaves the main sequence. A much rarer runaway helium fusion process can also occur on the surface of accreting white dwarf stars. Low-mass stars do not produce enough gravitational pressure to initiate normal helium fusion.
SN 1988Z was a prototypical [2] type IIn supernova event in the equatorial constellation of Leo. The apparent host is an irregular galaxy with the designation MCG +03-28-22. [1] It has a redshift of z equal to 0.0225. [1] This was a very luminous supernova that faded unusually slowly and has remained detectable three decades after the event.
Terraria also features seasonal events which activate during certain periods of the real world calendar year, adding new enemies and content. By completing specific goals, such as defeating a boss or obtaining a certain item, players can attract NPCs to occupy structures or rooms they have built, such as a merchant, nurse, or wizard. [ 3 ]
Type Ia supernova events occur when a white dwarf star accretes enough additional matter to exceed the Chandrasekhar limit and collapses, triggering runaway fusion and a supernova explosion. Because this collapse happens at a consistent mass, the resulting explosions have very uniform characteristics, and are used as " standard candles " to ...
SN 2013fs was recorded three hours after the supernova event on 6 October 2013, by the Intermediate Palomar Transient Factory. This is among the earliest supernovae caught after detonation, and it is the earliest for which spectra have been obtained, beginning six hours after the actual explosion.

Gravitational collapse of a massive star, resulting in a Type II supernova. Gravitational collapse is the contraction of an astronomical object due to the influence of its own gravity, which tends to draw matter inward toward the center of gravity. [1]
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.
