Black hole status of the Milky Way centre confirmed with striking new data
... of our galaxy, capturing concrete evidence of its existence is tough. But now thanks to new data from ESO’s GRAVITY instrument, a ring of extremely fast moving material has been spotted racing around near its event horizon at about...
