The team found that when jets launched from supermassive black holes strike hot gas between galaxies in galaxy clusters, called the "intracluster medium (ICM)," they carve out large cavities.

Using NASA's Chandra and ESA's XMM-Newton spacecraft, an international team of astronomers have performed X-ray observations of a nearby low-mass galaxy cluster designated PSZ2 G181.06+48.47.

NASA's Hubble Space Telescope has captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an 'arrow' -- a far smaller blue dwarf galaxy -- shot ...
