Journey to the closest pair of supermassive black holes
This video takes us to NGC 7727, a galaxy located 89 million light-years away from Earth in the constellation Aquarius and home to the closest pair of supermassive black holes found to date. The pair is also the one with the smallest separation between two supermassive black holes — observed to be just 1600 light-years apart in the sky.
Each of the two black holes is located at the centre of one of the two bright nuclei in NGC 7727 visible in the final part of the video. The two black holes are on a collision course, doomed to crash together and merge into one giant black hole probably within the next 250 million years.
