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 Jeans instability is a concept in astrophysics that describes an instability that leads to the gravitational collapse of a cloud of gas or dust. [1] It causes the collapse of interstellar gas clouds and subsequent star formation. It occurs when the internal gas pressure is not strong enough to prevent the gravitational collapse of a region ...
The barge has the capacity to hold 30,000 barrels, but was holding 23,000 barrels — approximately 966,000 gallons — when it struck the bridge, Rick Freed, the vice president of barge operator ...
The most basic gravitational stability analysis is the Jeans criteria, which addresses the balance between self-gravity and thermal pressure in a gas. In terms of the two above stability conditions, the system is stable if: i) thermal pressure balances the force of gravity, and ii) if the system is compressed slightly, the outward pressure ...
Barge hits bridge connecting Galveston and Pelican Island, causing partial collapse and oil spill By LEKAN OYEKANMI and JUAN LOZANO Associated Press GALVESTON, Texas (AP) — A barge slammed into a bridge pillar in Galveston, Texas, on Wednesday, spilling oil into waters near busy shipping channels and closing the only road to a small ...

Implosion is a key part of the gravitational collapse of large stars, which can lead to the creation of supernovas, neutron stars and black holes. In the most common case, the innermost part of a large star (called the core ) stops burning and without this source of heat , the forces holding electrons and protons apart are no longer strong ...
