A hundred years before the Event Horizon Telescope Collaboration released the first image of a black hole in 2019—located at the heart of the galaxy M87—astronomer Heber Curtis had already discovered ...

Back in 1971, the late physicist Stephen Hawking made an intriguing prediction: The total surface area of a black hole cannot decrease, only increase or remain stable. So if two black holes combine, ...

At the heart of nearly every galaxy lurks a cosmic giant: a supermassive black hole. These mysterious objects, millions to billions of times more massive than our Sun, exert such powerful gravity that ...

Stephen Hawking’s 50-year-old theorem on how black holes merge together has been successfully tested thanks to huge advances in gravitational wave astronomy, which helped astronomers catch the waves ...

Patricia Schmidt receives funding from UK Research and Innovation (UKRI) through grants ST/V005677/1 and ST/Y00423X/1, and The Royal Society through a Research Grant RG\R1\241327. Geraint Pratten is ...

An eon ago, when only microbes dwelled on Earth, a pair of black holes some 1.3 billion light-years beyond the solar system spiraled toward each other until they crashed. The two became one big black ...

"Having entirely new avenues to chase down is tremendous. Astronomy is full of surprises and never boring." Small black holes making a meal out of companion stars are surprisingly messy eaters, ...

Scientists have used a gravitational wave detector to "hear" two black holes getting bigger as they merged into a single, gigantic entity. The detection, made by the Laser Interferometer Gravitational ...

Supermassive black hole surrounded by accretion disk - El.artico/Shutterstock At the heart of nearly every galaxy lurks a cosmic giant: a supermassive black hole. These mysterious objects, millions to ...

Physicists have long believed that black holes explode at the end of their lives, and that such explosions happen—at most—only once every 100,000 years. But new research published in Physical Review ...

In 2020, astronomers identified a nearby star system that appeared to contain something phenomenal: the closest black hole to Earth! Now, new research from some of those same astronomers suggests that ...
