Astronomers using Chandra found that black holes may have squelched star formation in small, yet massive galaxies known as “red nuggets”. These are relics of the first massive galaxies that formed within only one billion years after the Big Bang, some of which have avoided merging with other galaxies throughout cosmic time. These images show the Chandra data and the Hubble data of one of the galaxies in the latest study, MRK 1216. Mrk 1216 is a relatively nearby red nugget clocking in at just 295 million light years away (or so).
