New data from NASA’s Chandra X-ray Observatory and ESO’s Very Large Telescope provide evidence that outbursts from supermassive black holes can help cool down gas to feed themselves. These images show two of the galaxy clusters in the study, the Perseus Cluster and the Centaurus Cluster. Chandra data represented in blue reveal X-rays from filaments of hot gas, and VLT data show cooler filaments in red. Image credit: NASA / CXC / SAO / Olivares...
