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 spacecraft cemetery, known more formally as the South Pacific Ocean(ic) Uninhabited Area, [1] [2] is a region in the southern Pacific Ocean east of New Zealand, [3] where spacecraft that have reached the end of their usefulness are routinely crashed.
Westerhout 51 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]
Simulated collision of two neutron stars. A stellar collision is the coming together of two stars [1] caused by stellar dynamics within a star cluster, or by the orbital decay of a binary star due to stellar mass loss or gravitational radiation, or by other mechanisms not yet well understood.
The Laniakea Supercluster (/ ˌ l ɑː n i. ə ˈ k eɪ. ə /; Hawaiian for "open skies" or "immense heaven") [2] or the Local Supercluster (LSC or LS) is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies.
The images show the surface of the star R. Doradus, a red giant star 180 light-years away in the Dorado constellation. The star has a diameter about 350 times that of the sun, and it serves as a ...
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.
Stars that collapse into neutron stars have a total mass of between 10 and 25 solar masses (M ☉), or possibly more for those that are especially rich in elements heavier than hydrogen and helium. [3] Once formed, neutron stars no longer actively generate heat and cool over time, but they may still evolve further through collisions or accretion.
