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 angular momentum of a stellar black hole is due to the conservation of angular momentum of the star or objects that produced it. The gravitational collapse of a star is a natural process that can produce a black hole. It is inevitable at the end of the life of a massive star when all stellar energy sources are exhausted.
Failed supernovae are thought to create stellar black holes by the collapsing of a red supergiant star in the early stages of a supernova. When the star can no longer support itself, the core collapses completely, forming a stellar-mass black hole, and consuming the nascent supernova without having the massive explosion. For a distant observer ...
Both Newton and Bentley thought that the stars did not move and did not consider stars in motion. [2] A finite number of mutually attracting stars in motion can indeed avoid collapse. [3] Today it is known that an infinite universe uniformly filled with gravitating matter, if it originated in a static configuration, would indeed collapse.
Astronomers were able to capture detailed observations of massive gas bubbles moving on the surface of a star, named R. Doradus, located 180 light-years away.
Experts say 2025 will be a particularly good year for the annual meteor shower as it will occur on a moonless night, allowing stargazers to see as many as 120 shooting stars per hour. Show ...
The Nobel Prize-winning event, [6] known as SN 1987A, was the collapse of a blue supergiant star Sanduleak -69° 202, in the Large Magellanic Cloud outside our Galaxy, 51 kpc away. [18] About 10 58 lightweight weakly-interacting neutrinos were produced, carrying away almost all of the energy of the supernova. [ 19 ]
