A strange black hole is making scientists scratch their heads. The distant object, dubbed "1ES 1927+654" and packing the mass of 1 million suns, previously stunned astronomers when its corona — a billion-degree cloud of rapidly moving particles enveloping a black hole — suddenly vanished.

A new study suggests more supermassive black holes may be lurking in the universe than previously thought. Astronomers from the University of Southampton have discovered that 35 per cent of these enormous entities—some of which are billions of times heavier than the sun—remain undetected.

At the center of almost every galaxy, there is a supermassive black hole. Well, astronomers think it’s every galaxy, but it is a difficult claim to confirm. Not because there might be many exceptions – the difficulty lies in the fact that many black holes are so well hidden that we wouldn’t know they are there.

The universe could be home to far more supermassive black holes than we realised, according to new research. Astronomers from the University of Southampton say that 35% of these galactic giants - some which are billions of times heavier than the sun - have gone undiscovered because they are obscured by thick clouds of gas and dust.

NASA telescopes reveal 35% of supermassive black holes are hidden by dust, reshaping theories about their role in galaxy growth.
