There is a smaller chance that the next core collapse supernova will be produced by a different type of massive star such as a yellow hypergiant, luminous blue variable, or Wolf–Rayet. The chances of the next supernova being a type Ia produced by a white dwarf are calculated to be about a third of those for a core collapse supernova.
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] Gravitational collapse is a fundamental mechanism for structure formation in the universe.
The Big Bang itself is a scientific theory, and as such, stands or falls by its agreement with observations. [2] However, as a theory which addresses the nature of the universe since its earliest discernible existence, the Big Bang carries possible theological implications regarding the concept of creation out of nothing.
Insets at lower right show one epoch of Webb observations, while the inset at left shows a Webb image of the central supernova remnant released in 2023. "Even as a star dies, its light endures ...
A Type II supernova or SNII [1] (plural: supernovae) results from the rapid collapse and violent explosion of a massive star. A star must have at least eight times, but no more than 40 to 50 times, the mass of the Sun ( M ☉ ) to undergo this type of explosion. [ 2 ]
Physicist Frank Tipler has proposed that the star of Bethlehem was a supernova or hypernova occurring in the nearby Andromeda Galaxy. [92] Although it is difficult to detect a supernova remnant in another galaxy, or obtain an accurate date of when it occurred, supernova remnants have been detected in Andromeda. [93]
When core collapse occurs in a star with a core at least around fifteen times the Sun's mass (M ☉) — though chemical composition and rotational rate are also significant — the explosion energy is insufficient to expel the outer layers of the star, and it will collapse into a black hole without producing a visible supernova outburst.
