Stephen Hawking was one of the greatest theoretical physicists of the modern age. Best known for his appearances in popular media and his lifelong battle against debilitating illness, his true...

Scientists hunting for elusive gravitational waves across the universe may be able to supercharge their discoveries with a new tool: artificial intelligence. Gravitational waves are ripples in spacetime, created when...

Sometimes in science when you set out to find something you had predicted, you instead find something quite different. This was the case recently when astronomers using the Hubble Space...

In the vicinity of black holes, space is so warped that even light rays may curve around them several times. This phenomenon may enable us to see multiple versions of...

Black holes are one of the most fascinating and mind-bending phenomena in the universe. The gravity of a black hole is so powerful that not even light can escape it....

The researchers Juan A. Fernández-Ontiveros, of the Istituto Nazionale di Astrofisica (INAF) in Rome and Teo Muñoz-Darias, of the Instituto de Astrofísica de Canarias (IAC), have written an article in...

A pair of orbiting black holes millions of times the Sun’s mass perform a hypnotic pas de deux in a new NASA visualization. The movie traces how the black holes...

General relativity, Einstein’s theory of gravity, is best tested at its most extreme—close to the event horizon of a black hole. This regime is accessible through observations of shadows of...

Using the SRG/eROSITA all-sky survey data, scientists at the Max Planck Institute for Extraterrestrial Physics have found two previously quiescent galaxies that now show quasi-periodic eruptions. The nuclei of these...

On Sept. 9, 2018, astronomers spotted a flash from a galaxy 860 million light years away. The source was a supermassive black hole about 50 million times the mass of...
