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.
When black holes collide, gravitational waves are created in space itself (image is a computer simulation).

Einstein called entanglement "spooky action at a distance”. But now it's been used to design an incredibly sensitive detection method for gravitational waves.
Disappointed about Doctor Who's TARDIS ending up at the wrong place at the wrong time? Don't be – it's incredibly precise.
The discovery of the year was the first detection of gravitational waves.
Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.
Hi Juno, welcome to Jupiter.
From the discovery of gravitational waves, to the Pokémon Go phenomenon to the Census debacle, it's been a big year in science and technology.
Einstein’s theories are still not taught in school.
Einstein's theories of relativity underpin our understanding of the universe, yet they're not taught in high school. How can we change that?
Truth is out there.
Sonification is a technique for converting data into sound. It could transform the study of distant worlds.
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.
State of the art detectors have found another signal from a pair of collapsing black holes – the consequences could be momentous.
We find them at the beach, in every sound and light show, the miracle of wi-fi and now in the fabric of space-time itself. But what exactly is a wave?
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.

Why gravitational waves from the birth of the universe are a whole different story than the waves LIGO detected.
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.
Einstein claimed that, had he not pursued science, he would have been a musician.

Einstein, an accomplished violinist, claimed that, had he not pursued science, he would have been a musician. That's worth reflecting on, in the wake of last week's discovery of gravitational waves.
Music has always played a part in investigating the universe.

Music has always played a role in our understanding of the universe. Listening to gravitational waves confirms thousands of years of metaphysical investigation.
There's a good reason you should care about the discovery of gravitational waves, even if you don't understand the science.
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.
