A cosmic fountain is just as cool as it sounds — and stunningly beautiful to match. When vast amounts of gas fall toward a supermassive black hole at the center of a galaxy cluster, gravitational and electromagnetic forces spray most of the gas away continuously for tens of millions of years. Scientists combined data from X-ray, radio, and optical telescopes (including @nasachandraxray!) to confirm the first clear evidence for the simultaneous inward and outward flow of gas being driven by a supermassive black hole!-NASA
