For the first time, astronomers have detected billowy clouds of cold, clumpy gas streaming toward a black hole, at the center of a massive galaxy cluster. The clouds are traveling at up to 355km/s and may be only 150 light years away from its edge, almost certain to fall into the black hole. The observations represent the first direct evidence to support the hypothesis that black holes feed on clouds of cold gas...
