"Unveiling the Universe's Heaviest Black Hole Binary: A 28 Billion Solar Mass Marvel"

Astronomers have discovered a galaxy hosting the heftiest pair of supermassive black holes ever seen, with a combined mass of 28 billion times that of the Sun. The binary black holes, located in a galaxy called B2 0402+379, exhibit peculiar properties that are helping scientists understand the process of black hole growth. The discovery suggests a potential solution to the final parsec problem, as the orbital decay of the binary has stalled due to the lack of nearby stars and gas to transfer orbital momentum. Further investigations will focus on determining whether the supermassive black holes can eventually merge or will remain stranded as a binary.
