When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were ...

A strange chirp detected by LIGO in 2019 has some scientists searching for answers beyond a simple black hole merger.

In May 2019, astronomers picked up something strange in the fabric of spacetime. The LIGO and Virgo detectors recorded a gravitational wave that lasted just one-tenth of a second. The signal, known as ...

Deep in the core of most galaxies, hidden by spinning clouds of gas and dust, black holes spin like cosmic engines. These ...

Nobel laureate Kip Thorne, who will deliver the Royal Irish Academy 2025 Hamilton Lecture, on his lifelong quest to ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions. Scientists tracked the complete cosmic collision, confirming that black ...

The magnetic field swirling around an enormous black hole, located about 55 million light-years from Earth, has unexpectedly switched directions. This dramatic reversal challenges theories of black ...

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 ...

Astronomy has a way of surprising you. When you believe the universe has yielded its biggest secrets, distant giants and faint signals come along to pose even more questions. Two recent discoveries ...

Black Hole Sign is, on the surface, a fairly conventional drama about the state of the NHS. It’s set in a hospital ward during a night shift at a time when the service is overstretched and the nurses ...

Scientists have recently uncovered groundbreaking insights into the core of black holes, potentially resolving one of the universe’s greatest mysteries. As research advances, predictions indicate that ...

The supermassive black hole is that first one that astronomers ever photographed. For more than a century, astronomers have marveled at the brilliant jet of matter blasting from the heart of the giant ...
