Abell 2597 is a galaxy cluster located about a billion light years from Earth in the constellation of Aquarius. [3] It is a giant elliptical galaxy that is surrounded by a sprawling cluster of other galaxies. [4] In 2018, the National Radio Astronomy Observatory (NRAO) captured cosmic weather event using the Atacama Large Millimeter/submillimeter Array (ALMA) that has never been seen before - a cluster of towering intergalactic gas clouds raining in on the supermassive black hole at the center of the huge galaxy. [4] [5] The black hole draws in vast store of cold molecular gas and sprays it back again in an ongoing cycle [6] so that it resembles a gigantic fountain.
