GREENBELT, Md., Feb. 6 (UPI) -- NASA says its Chandra X-ray Observatory has revisited a galaxy 12 million light years from Earth with a giant jet blasting away from a supermassive black hole.
Just weeks after NASA's Chandra X-ray Observatory began operations in 1999, the telescope pointed at Centaurus A, and has periodically returned its attention to the object, gathering more data each time.
