Black holes are regions of space where gravity is so strong that it sucks everything in, including light. They result from the exploding of a large star in its final stages of life. Such an explosionis known as supernovae. It scatters most of a star into the void space but leaves behind a large ‘COLD’ remnant.
Even the light from the star is unable to escape its gravitational pull and becomes trapped in orbit. The dark star becomes known as a black hole. In 1998, astronomers found evidence that a supermassive black hole, weighing about 4 million solar masses, is located in the center of our home galaxy, the milky way.
Matter spiralling into a black hole is torn apart and glows so brightly that it creates the brightest objects in the universe – quasar. A black hole cannot be viewed directly because light cannot escape it. Scientists detect a black hole because it swallow gas from nearby stars and emits X-rays. Cygus x-1 is the black hole that is located about 8000 light years away from our planet earth. This is the closest black hole to earth, known to man.
