Using our Chandra X-ray Observatory, astronomers have found that the growth of galaxies, including Abell 2597 shown here, containing supermassive black holes can be slowed down by a phenomenon referred to as cosmic precipitation.

Cosmic precipitation is not a weather event, as we commonly associate the word -- rain, sleet, or snow. Rather, it is a mechanism that allows hot gas to produce showers of cool gas clouds that fall into a galaxy. Researchers have analyzed X-rays from more than 200 galaxy clusters, and believe that this gaseous precipitation is key to understanding how giant black holes affect the growth of galaxies.
