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.
Merging supermassive black holes would emit gravitational waves, allowing scientists to detect them.
Astronomers are now able to detect a host of signals streaming through the universe. This newfound ability is like gaining new senses and it's opening the door to understanding the cosmos.
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.
To better detect gravitational waves, we need to build the quietest and most isolated thing on Earth. And make sure we don't drop those 40kg mirrors.
Astronomers are getting ready to say good bye to the radio emission from a neutron star merger – one of the most energetic events in the universe – that was detected last year.
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?
Cosmologists who were hoping to be the next Einstein have had to bin their theories.
Until the recent observation of merging neutron stars, how the heaviest elements come to be was a mystery. But their fingerprints are all over this cosmic collision.
A LIGO team member describes how the detection of a gravitational wave from a new source – merging neutron stars – vaults astronomy into a new era of 'multi-messenger' observations.
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.
The gravitational wave itself is the least exciting part of the announcement from LIGO and Virgo. Observing this new source answers many longstanding questions.
The discovery of tiny ripples in space from the violent collision of dense stars could help solve many mysteries – including where the gold in our jewellery comes from.
The 2017 Nobel Prize for Physics was awarded to scientists who helped pioneer the discovery of gravitational waves. Australia is playing an important role in gravitational-wave astronomy.
Razor-sharp, unconventional and fun on the dance floor. A colleague paints a colourful portrait of one of this year's Nobel Laureates in physics.
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.
Atoms blown up in the right way could signal when a gravitational wave is passing through.
