But they are making a comeback in some areas – and photographers and scientists are capturing unprecedented images of them. In 2020, wildlife photographer Vladimír Čech Jr was trudging through the snow in a military zone in the Doupov Mountains, a remote and rugged area in the Czech Republic.

Containing about 30 galaxies including three with supermassive black holes (depicted here with jets), the cluster is filled with an extraordinarily hot gas (illustrated here in red).   (Image credit: Lingxiao Yuan.) The galaxy cluster appears hotter and more mature than it should for its young age, challenging what we think we know about how these cities of galaxies form. A seemingly impossible cluster of more than 30 galaxies crammed into a volume just 500,000 light-years across has been found in the universe just 1.4 billion years after the Big Bang  —  and with a temperature that breaks all the rules. The discovery, by astronomers using Chile's Atacama Large Millimeter/submillimeter Array ( ALMA ), of the  galaxy  cluster labeled SPT2349-56 challenges our understanding of how quickly gal...
