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.
The Australia Telescope Compact Array in Narrabri, NSW.
All it took was a single email alert to send the world's astronomers searching for the source of the latest gravitational wave detected.
The Zadko telescope was set to study the optical glow following a gamma ray burst.
Efforts to see the afterglow from a neutron star merger were nearly thwarted by bad weather and a cyber attack on an Australian telescope.
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.
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.

A burst of gamma rays in a distant part of the universe reveals the birth of another black hole.
We don’t know what the black hole at the centre of the Milky Way will look like.
The first ever picture of the Milky Way's black hole is expected to be a bright crescent shape rather than a disk.

The discovery of a new black hole adds to our understanding of these celestial objects that fascinate in both fact and fiction.
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?
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.
Windy black hole.
It was a rare and brief event, but powerful telescopes helped scientists get a glimpse of a black hole letting out a wind at 3,000km per second.
All is not calm in the cosmos.

Stargazing seems such a quiet, calm activity. But whether our eyes can see or not, those stars out there are in constant flux. Time-domain astronomy studies how cosmic objects change with time.
A new development could mean vastly increase data transfer over optical fibre cables.
The design of a new chip to detect the twisted nature of light waves could pave the way for next generation of optical communication technologies.
The High Energy Stereoscopic System (HESS) was instrumental in determining the origin of cosmic rays.
A new study suggests that mysterious high energy cosmic rays might originate from the supermassive black hole at the centre of our galaxy.
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.
