Astronomers led by Prof Joss Bland-Hawthorn from the University of Sydney have found evidence that the supermassive black hole at the heart of our galaxy, known as Sagittarius A*, erupted in a colossal explosion around 2 million years ago. The explosion was so powerful that it lit up a cloud 200,000 light years away. This is an artist’s conception of a black hole generating a jet. Two million years ago Sagittarius A* – the supermassive...
