Gravity betrays black heart of Milky Way

PARIS: Studies of the movement of stars provide the best evidence yet that a huge, gravity-sucking hole sits at the heart of our galaxy.

The observations, to be published in the Astrophysical Journal, also offer the best proof that supermassive black holes – among the most enigmatic and powerful forces in the universe – really do exist.

By tracking the orbit of 28 stars inside the Milky Way for more than 16 years, scientists in Germany were able to trace the most detailed portrait ever obtained of these invisible monsters.
