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 ]
G299.2-2.9 is a supernova remnant in the Milky Way, 16,000 light years from Earth. [2] It is the remains of a Type Ia supernova . [ 3 ] The observed radius of the remnant shell translates to approximately 4,500 years of expansion, [ 4 ] making it one of the oldest observed Type Ia supernova remnants.

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]
The supernova exploded when the universe was 3.5 billion years old, rather than at today's date of 13.8 billion years old. The supernova progenitor was a white dwarf star, the progenitor of all Type Ia supernovae. The gravitational lens is galaxy cluster PLCK G165.7+67.0 (at a redshift of z=0.35), which lensed the supernova and its host galaxy ...
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 ...
The event was positioned at an offset of 15″ west and 78″ south of the galactic nucleus of M51. [2] Based on the data, the explosion was inferred to occur 2.8 days before discovery. [ 6 ] It was considered under-luminous for a supernova of its type, releasing an estimated 3 × 10 50 erg in energy.
