Black Hole

  1. 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.
  2. Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape.
  3. Apr 10,  · In April , scientists used a global network of telescopes to see and capture the first-ever picture of a black hole, according to an announcement by .
  4. 2 days ago · Supermassive black holes dot our universe, monstrous gravity wells that bind galaxies together and wreath themselves in whirling cocoons of dust that emit bright X-ray beams. Sometimes, bright.
  5. Black Holes. A black hole is a location in space that possesses so much gravity, nothing can escape its pull, even light. Learn more about what black holes are and the latest news.
  6. Dec 03,  · Much like stars and planets, black holes also fall into different categories. Astronomers have now spotted a record-breaking heavyweight black hole at the center of a galaxy known as Holm 15A.
  7. Sep 21,  · Gravitational wave ‘tones’ detected following the merger of two black holes confirm the decades-old ‘no-hair theory’ of black hole properties. For the first time, astrophysicists have heard a black hole ringing like a bell.
  8. Mar 06,  · A black hole is formed when a star of sufficient mass undergoes gravitational collapse, with most or all of its mass compressed into a sufficiently small area of space, causing infinite spacetime curvature at that point (a "singularity").
  9. Primordial black holes Formed from the condensation of raw materials in the early cosmos, primordial black holes emerged soon after the Big Bang. Most were extremely tiny, and while those with the lowest-mass have likely evaporated, primordial black holes with larger masses may still exist â though even those have remained undetected.
