BLACK HOLE...!!!

BLACK HOLE:
A black hole is a region of spacetime where gravity is so strong that nothing that enters the region, not even light, can escape.The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return. It is called "black" because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics...Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater

BLACK HOLE COUGHT EATING STARS:
A super massive black hole has been caught in the act of swallowing up a red giant star. ASTRONOMERS HAVE WITNESSED a rare galactic homicide: a super massive black hole devouring an orbiting star that ventured just a little too close. Such events only occur once every 10,000 years and scientists from the USA were fortunate enough to catch the star's demise in action.
Lurking in the centre of a galaxy some 2.7 billion light-years from Earth, this super massive black hole has finally broken its fast by shredding and devouring a red giant star.
The team was looking for a bright flare in ultraviolet light from the nucleus of a galaxy, which is a lingering clue that a black hole has consumed a star. Instead, they discovered an active black hole in the process of consuming a star. The brightness of the glow indicates that the black hole contains three million times as much mass as our own Sun, making it about the same size as the black hole at the centre of the Milky Way.

If a star passes too close to a black hole, it is ripped apart by gravitational forces. Its constituent gases then swirl in toward the black hole generating heat and light before being sucked into the abyss. It is this glow that astronomers search for in their quest to catch an active black hole in the act of consuming a star.
