A black hole, or multiple holes, created these dark voids. But astronomers don't know precisely how the unusual structures were formed.
X-ray: NASA/CXC/Univ. of Bologna/F. Ubertosi; Optical: NASA/STScl/M.CalzadillaLarge dark spots form the shape of a four-leaf clover in the middle of a cluster of galaxies, according to a new study. It’s a cosmic first–the only time scientists have observed two sets of such dark spots, which are formed by black holes, in the same place.
The galaxy cluster in question, called RBS 797, is 3.9 billion light-years from Earth and has been well studied already. Researchers have long known that radio lobes existed there. In particular, Ubertosi’s work builds off aof the region, which found that X-ray voids overlapped with the lobes—places that were dark to the Chandra X-ray Observatory. This supported the idea that a black hole there had “excavated” the surrounding matter out of the region, Ubertosi says.
In 2019, Ubertosi’s supervisor was awarded time on the Chandra space telescope to check out the object in more detail. And when they got the results, they saw four voids in Chandra’s X-ray readings, matching the four radio lobes.
