A global team of radio astronomers have on Thursday unveiled the first image of the supermassive black hole at the centre of the Milky Way galaxy.
Scientists had previously seen stars orbiting around something invisible, compact, and very massive at the centre of the Milky Way.
But the image of Sagittarius A (Sgr A) which is about 27,000 light-years away from Earth, produced by a global research team called the Event Horizon Telescope (EHT) Collaboration, provides the first direct visual evidence of it.
