A jet of X-rays from a supermassive black hole 12.4 billion light years from Earth has been detected by NASA's Chandra X-ray Observatory. This is the most distant X-ray jet ever observed and gives astronomers a glimpse into the explosive activity associated with the growth of supermassive black holes in the early universe.
