Recent observations from NASA’s Neil Gehrels Swift Observatory have unveiled remarkable activity centered around a pair of gigantic black holes disrupting a gas cloud in a remote galaxy. Astrophysicists, including Lorena Hernández-García from the Millennium Institute of Astrophysics in Chile, have described this strange cosmic event, dubbed AT 2021hdr, which recurs intermittently every few months.
Located in the galaxy 2MASX J21240027+3409114—approximately 1 billion light-years away in the constellation Cygnus—these supermassive black holes, with a combined mass 40 million times that of our Sun, are separated by roughly 16 billion miles. The researchers estimate the black holes complete an orbit every 130 days and expect a future collision in about 70,000 years.
Initially reported as a possible supernova by a team at Caltech, subsequent observations have refined their understanding, leading to the conclusion that the black holes are pulling apart a gas cloud larger than themselves. As the gas interacts with the black holes, it becomes heated and illuminated, generating distinctive bursts of light detectable in various wavelengths.
Continuous research aims to dissect the intricate dynamics of AT 2021hdr while also shedding light on its host galaxy, which is in a merger process. As NASA’s Swift mission nears its 20th anniversary, its contributions to unveiling cosmic mysteries continue to impress astronomers around the globe.
