"This is truly extraordinary," Itai Sfaradi of the University of California, Berkeley, said in a statement. "Never before ...

A new study may visually solve an enduring mystery about a bright object that's been studied since the 19th century ...

Ten years after the first detection of gravitational waves, scientists have captured the clearest signal yet — and it confirms one of Stephen Hawking’s most famous predictions. Using the upgraded LIGO ...

A black hole far from its galactic center has unleashed the fastest, brightest radio flares ever seen from a star’s destruction. For the first time, astronomers have detected a tidal disruption event ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or mathematician to tell you about fascinating ideas from their corner of the ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

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 ...

A black hole analog could tell us a thing or two about an elusive radiation theoretically emitted by the real thing. Using a chain of atoms in single file to simulate the event horizon of a black hole ...

New data from the James Webb Space Telescope may solve a riddle from the universe’s beginnings. A compact, distant object called “The Cliff” appears to show that many of the mysterious “little red ...

Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays — the most powerful particles known in the universe. A team from NTNU suggests that colossal winds from ...
