Multiple NASA telescopes recently helped scientists search the sky for supermassive black holes—those up to billions of times heavier than the sun. The new survey is unique because it was as likely to find massive black holes that are hidden behind thick clouds of gas and dust as those that are not.

Researchers found far more hidden black holes than previously known, indicating plenty of behemoths lurking in thick clouds of gas and dust.

A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?

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

The universe could be home to far more supermassive black holes than we realised, according to new research. Many of them are hidden beyond our view, the researchers suggest – which might mean that we have dramatically undercounted how many swirling voids are present in our cosmos.
