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.
New processing techniques applied to years of Chandra's observations are providing a new look at this old galactic friend, NASA said in a release Thursday.
This new image of Centaurus A contains data from observations, equivalent to over nine and a half days worth of time, taken between 1999 and 2012, NASA said.
