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 found something not predicted by current theory when they took a closer look at the emissions from a neutron star with a very strong magnetic field.
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.
An extreme laboratory in space involving three dead stars has shown that all objects really do accelerate identically, proving Einstein right.
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.
Pulsars are rapidly rotating neutron stars and some of them are know to have a "glitch", and astronomers have captured one as it hapened.
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.
By figuring out fission, physicists were able to split uranium atoms and release massive amounts of energy. This Manhattan Project work paved the way both for atomic bombs and nuclear power reactors.
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.
Studying mysterious neutron stars could uncover the secrets of exotic physics – and a way to navigate the stars.
State of the art detectors have found another signal from a pair of collapsing black holes – the consequences could be momentous.
A new study has failed to find evidence of gravitational waves, but that doesn't mean Einstein was wrong about their existence.
