A team of astronomers captured the moment when a wayward star was pulled into the mouth of a supermassive black hole.
Astronomers are gathering an exponentially greater amount of data every day – so much that it will take years to uncover all the hidden signals buried in the archives.
The little-known Rossi X-ray Timing Explorer spacecraft was like a Geiger counter for the universe, listening to black holes and zombie stars.
Stephen Hawking raised the public profile of grand science, and speculated about the future of artificial intelligence, as well as contacting aliens. Does science mix easily with science fiction?
There could be thousands of black holes at the heart of the Milky Way.
The famous cosmologist was closely identified with black holes due to his revolutionary theoretical work explaining some of their mysterious properties.
Despite his fears artificial intelligence might one day overtake humanity, Stephen Hawking knew from his own life how profoundly AI could improve humans' daily lives.
UK's Astronomer Royal Martin Rees shares his memories of the physicist Stephen Hawking, who has died at the age of 76.
Stephen Hawking inspired people with his work on black holes and other mysteries of the universe. Many were quick to pay tribute to the theoretical physicist who died today in the UK, aged 76.
Hawking's most famous book, A Brief History of Time, sold 10 million copies and was translated into 40 languages, skyrocketing to the top of the bestseller lists in the US and UK.
From a slow hum to a chirp or a bleep, what is that sound you hear whenever there's a new detection of gravitational waves?
Jets from supermassive black holes behave in mysterious ways. Now scientists have now worked out what's really going on.
Black holes may come in many sizes, but there's still a gap in the middle. The hunt is on to solve the mystery of where are the intermediate size black holes.
Hawking proved that the Big Bang was physically possible.
Astronomers have finally confirmed the source of the latest detected gravitational waves was the collission of a pair of neutron stars, what they'd been searching for all along.
All it took was a single email alert to send the world's astronomers searching for the source of the latest gravitational wave detected.
Efforts to see the afterglow from a neutron star merger were nearly thwarted by bad weather and a cyber attack on an Australian telescope.
New results from Italy and the US help us better estimate the position of the merging black holes that produced the gravitational waves.
New research shows that as few as ten further detections of gravitational waves will help scientists know for sure how pairs of black holes form.
Scientists have made a third detection of gravitational waves, again caused by the merger of two black holes. But they think there's something different about the black holes in this case.
