bubbles blown by black hole

A relatively small black hole has been spotted blowing bubbles with diameters of more than 300-1500 light years.Robert Soria of the University College London and colleagues pored over images and data from the European Southern Observatory and Chandra X-ray Observatory, zeroing in on an unusually large remnant from a supernova explosion. Its host galaxy appears in the Sculptor constellation of Earth's southern sky, around 12.7 million light years away.
