Best view yet of dusty cloud passing galactic center black hole
Paris (SPX) Mar 28, 2015
A supermassive black hole with a mass four million times that of the Sun lies at the heart of the Milky Way galaxy. It is orbited by a small group of bright stars and, in addition, an enigmatic dusty cloud, known as G2, has been tracked on its fall towards the black hole over the last few years. Closest approach, known as peribothron, was predicted to be in May 2014. The great tidal forces in this region of very strong gravity were expected to tear the cloud apart and disperse it along its orbit. ... read more
