Hace 3 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 2 días · A black hole is a region of spacetime where gravity is so strong that nothing, not even light and other electromagnetic waves, is capable of possessing enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Hace 2 días · Black holes are remarkable astronomical objects with gravity so strong that nothing, not even light, can escape them. The most gigantic ones, known as “supermassive” black holes, can weigh millions to billions times the mass of the Sun. These giants usually live in the centers of galaxies.Our own galaxy, the Milky Way, contains a supermassive black hole in its heart as well.

Hace 5 días · Observations of seven fast-moving stars at the center of a dense star cluster in the Milky Way reveal the presence of an intermediate-mass black hole, perhaps the most puzzling class of these dark objects.
Hace 5 días · A massive black hole – about 20,000 times the size of the sun – has been confirmed as the closest to our solar system by an international study involving University of Queensland researchers.
