An ultramassive black hole, understood to be one of the largest ever detected, has been discovered by astronomers using a new technique
The findings, published by the Royal Astronomical Society, show that the black hole is more than 30 billion times the mass of the sun – a scale rarely seen by astronomers. The researchers described it as an “extremely exciting” discovery that opens up “tantalizing” possibilities for detecting further black holes.
“Most of the biggest black holes that we know about are in an active state, where matter pulled in close to the black hole heats up and releases energy in the form of light, X-rays, and other radiation,” Nightingale added. “However, gravitational lensing makes it possible to study inactive black holes, something not currently possible in distant galaxies.
