The new class of black hole is so large that it has an equivalent mass of up to 40 billion suns.
It has long been believed that supermassive black holes exist in the centre of many galaxies, but not even these can compare to the scale of the ultramassive class of black hole. Exponentially larger than anything else ever found, these behemoths of the cosmos appear to be located in far off galaxies more than 1.3 billion light years from the Earth.
A recent study conducted by researchers at Stanford University identified ultramassive black holes in 10 out of 18 galaxies investigated. "Ultramassive black holes - that is, black holes with masses exceeding 10 billion solar masses - are probably not rare; several and even dozens of these colossal black holes may exist," said study author Julie Hlavacek-Larrondo.
"It turns out that the largest black holes may be even bigger than scientists previously thought."
