Hace 4 días · Based on mass and increasingly precise radius limits, astronomers have concluded that Sagittarius A* must be the central supermassive black hole of the Milky Way galaxy. The current value of its mass is 4.297 ± 0.012 million solar masses .
Hace 3 días · A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, is capable of possessing enough energy to escape it. [2] Einstein 's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Hace 4 días · A supermassive black hole (SMBH or sometimes SBH) is the largest type of black hole, with its mass being on the order of hundreds of thousands, or millions to billions, of times the mass of the Sun (M ☉). Black holes are a class of astronomical objects that have undergone gravitational collapse, leaving behind spheroidal regions of ...
Hace 2 días · Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a massive star wherein its core gravitationally collapses inward upon itself, compressing to a point of zero volume and infinite density called the singularity.
Hace 4 días · supermassive black hole (SMBH), a black hole more than one hundred thousand times the mass of the Sun. Nearly every large galaxy has a supermassive black hole at its centre. Active galactic nuclei , such as Seyfert galaxies and quasars , are powered by supermassive black holes.
6 de may. de 2024 · A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives. The energy that held the star together disappears and it collapses in on itself producing a magnificent explosion. Here’s where things get crazy.
