Centaurus A
Extended X-Ray Jet in Nearby Galaxy Reveals Energy Source
At a distance of 11 million light years, Centaurus A or NGC 5128, is the nearest example of a type of galaxy called an active galaxy. It is a large elliptically shaped galaxy that shows evidence of repeated explosions, probably from a supermassive black hole in the center of the galaxy. Radio and X-ray images of the galaxy show a jet of high-energy particles blasting out from the center. Because of its unusual nature and proximity, it is one of the most extensively studied galaxies in the southern hemisphere.
