Black Hole Confirmed in Milky Way

There is a giant black hole at the center of our galaxy, a 16 year study by a German astronomers has confirmed. They tracked the movement of 28 stars circling the center of the Milky Way, using two telescopes in Chile. The black hole, said to be 27,000 light years from Earth, is four million times bigger than the Sun.
Black holes are objects whose gravity is so great that nothing, including light, can escape them. Dr Massey said: "Although we think of black holes as somehow threatening, in the sense that if you get too close to one you are in trouble, they may have had a role in helping galaxies to form. Not just our own, but all galaxies. The researchers from the Max Planck Institute for Extraterrestrial Physics in Germany said the black hole was 27,000 light years from the Earth.
