More ripples in space-time have been detected from merging pairs of black holes, one of which was the most massive and distant gravitational-wave source ever observed.
Astronomers have suspected them for ages –now a team as finally spotted a ‘fountain’ in a galaxy far, far away.
The Swift Observatory passed a milestone: 1 million snapshots of the universe. These exquisite and revealing pictures have captured the births and deaths of stars, gravitational waves and comets.
It’s all about the strong gravitational field of the black hole.
A detector buried under more than a mile of ice in Antarctica has detected a high-energy subatomic neutrino and traced it to its origin, a blazar – a gargantuan black hole more than a billion times more massive than the sun.
The pull created by a black hole is so strong that if you get too close to one – even if you are travelling away from it at the fastest speed it is possible to go – you will never be able escape.
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.
