Since Hitomi measured the motion of gases in the cluster's core, the astronomers also figured out the reason why stars aren't abundant in that area. Apparently, the supermassive black hole keeps stirring those gases, preventing them from cooling down enough to form new stars. The astronomers wrote about their findings in Nature, and they expect to be able to share more in the future. Unfortunately, Japan's space agency gave up trying to rescue the telescope way back in April. Once the scientists have exhausted what little data it collected, we'll have to say goodbye to Hitomi for good.
