Super massive Black Hole staked out by Desert Scope

PARIS: A desert telescope has focused with unprecedented sharpness on a star circling a supermassive black hole thought to lurk at the centre of our Milky Way galaxy, excited astronomers announced on Wednesday.

This means they will be able to observe the star’s movements in more detail than ever before, in an important test for Albert Einstein’s theory of general relativity.

Dubbed S2, the star lies about 25,000 light years from our Solar System.It is the celestial body known to make the closest approach to our galaxy’s central black hole, named Sagittarius A, on a 16-year elliptical orbit.S2 is a relative youngster in astronomical terms — no more than 100 million years old.
