Astronomers have revealed the first visual of a supermassive black hole at the centre of the Milky Way the Earth’s galaxy. Known as Sagittarius A* (Sagittarius A-star), the object is four million times the mass of the Earth’s Sun.Scientists had to literally chase shadows in deep space to get a close look at the black hole – a collapsed star from which not even light can escape because of its incredible gravity.Black holes are regions in space where gravity’s pull is so intense that nothing, including light, can escape.Though the presence of a black hole was thought to be the only plausible explanation, the new image provides the first direct visual proof. The black hole is 27,000 light years from Earth.
