This image show stars orbiting very close to Sgr A* (centre), the supermassive black hole at the heart of the Milky Way. They were obtained with the GRAVITY instrument on ESO???s Very Large Telescope Interferometer (VLTI) at the end of March 2021.

We’ve seen our galaxy’s huge black hole more clearly than ever before

Astronomers have observed Sagittarius A* – the supermassive black hole at the centre of our galaxy – closer than ever before, and Albert Einstein’s general theory of relativity still holds up

Close-up view of the two bright galactic nuclei, each housing a supermassive black hole, in NGC 7727, a galaxy located 89 million light-years away from Earth in the constellation Aquarius. Each nucleus consists of a dense group of stars with a supermassive black hole at its centre. The two black holes are on a collision course and form the closest pair of supermassive black holes found to date. It is also the pair with the smallest separation between two supermassive black holes ??? observed just 1600 light-years apart in the sky.???? The image was taken with the MUSE instrument on ESO???s Very Large Telescope (VLT) at the Paranal Observatory in Chile.
