Astronomers have confirmed the existence of an ultramassive black hole, potentially the largest ever observed, boasting a mass equivalent to 36 billion suns. The discovery was made possible through a combination of gravitational lensing, where the black hole's gravity distorts light from background galaxies, and stellar dynamics, which analyzes the movement of stars within the host galaxy. This behemoth challenges existing models of black hole formation and provides valuable insights into the evolution of galaxies and the supermassive black holes at their centers.
