The colossal black hole, estimated to have a mass 32.7 billion times that of the Sun, is situated in the heart of a galaxy 2.7 billion light-years away from Earth. Although the existence of this cosmic giant had been known since 2004, its true dimensions were only recently revealed thanks to a combination of Hubble Telescope images and advanced computer simulations using the DiRAC HPC COSMA8 supercomputer.
This impressive black hole ranks among the top ten largest ever discovered, with its mass determined to be a staggering 7 billion solar masses larger than previous estimates. The advanced investigative techniques employed, including gravitational lensing, allowed researchers to accurately determine the black hole's mass and better understand its enormous size.
Located at the center of the Abell 1021 BCG galaxy, a widespread elliptical galaxy and the most luminous in its cluster, this ultramassive black hole lies within the heart of the Abel 1201 galaxy cluster. To gauge its size, scientists analyzed the distortions of light produced by spacetime, ultimately unveiling a black hole with an event horizon spanning a diameter of 195 billion kilometers (1,300 astronomical units).
As a landmark astronomical discovery, this immense black hole has captured the attention of both scientists and the public alike, broadening our understanding of the cosmos and revealing the true scale of the universe's most enigmatic and powerful phenomena.
