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.

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.

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.
Virgo detector in Italy.
New results from Italy and the US help us better estimate the position of the merging black holes that produced the gravitational waves.
Black hole collision and merger releasing 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.

These ripples in the very fabric of the universe were hypothesized by Einstein a century ago. Now scientists have detected them for the third time in a year and a half – ushering in a new era in astrophysics.
Gravitational waves are produced by some of the most extreme events in the universe.
The OzGRav Centre of Excellence for Gravitational Wave Discovery will enable Australian researchers to be at the forefront of gravitational wave astronomy.
An illustration showing the merger of two black holes and the gravitational waves that ripple outward.
The observation of gravitational waves from a second black hole merger implies there are many more black holes in the universe than scientists had previously anticipated.
Children are natural scientists. They learn from their mistakes, then try something new.
Scientists being wrong is not a bug or a glitch – it's a feature of science and mistakes can actually lead to new, deeper discoveries.
It’s a lot of grains of sand, but numbers can get a whole lot bigger….
Scientific advances – including the recent discovery of gravitational waves – force us to deal with numbers so extreme they're virtually inconceivable.
A needle in a haystack? Pan Starrs telescope is scanning billions of galaxies to find the black holes emitting gravitational waves.
The hunt to find the source of the gravitational waves detected by LIGO on the sky is only just starting.
This is a new era of physics and astronomy - and scientists all over the globe, including in Africa, have a role to play.
The discovery of gravitational waves has ushered in a new era in astronomy and physics. Where will the next big discovery be made? There's no reason for it not to be Africa.
A team effort: Dr David Reitze, of the LIGO Laboratory at Caltech, shows the merging of two black holes that led to the detection of gravitational waves.
The discovery of gravitational waves involved a team of more than 1,000 scientists from across the globe, including Australia. So how does such an international collaboration work?

It's taken centuries for our understanding of gravity to evolve to where it is today, culminating in the discovery of gravitational waves, as predicted by Albert Einstein a century ago.

Sometimes big research news bypasses the usual scientific publishing process. Here's why that's not good for scientists or the public.
Oh hey, I heard ripples in space and time, generated as two black holes merged. Call me back.
Here's a LIGO insider's description of how he got the news of a phenomenon that had first been theorized 100 years ago.
