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.
Hartland Sweet Snyder (1913 – May 22, 1962) was an American physicist [1] who, together with J. Robert Oppenheimer, showed how large stars would collapse to form black holes. [2] This work modeled the gravitational collapse of a pressure-free homogeneous fluid sphere and found that it would be unable to communicate with the rest of the ...
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.
The W51 nebula in Aquila - one of the largest star factories in the Milky Way (August 25, 2020). Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as "stellar nurseries" or "star-forming regions", collapse and form stars. [1]

The second, the Stelliferous Era, includes the present day and all of the stars and galaxies now seen. It is the time during which stars form from collapsing clouds of gas. In the subsequent Degenerate Era, the stars will have burnt out, leaving all stellar-mass objects as stellar remnants—white dwarfs, neutron stars, and black holes.
