Triple star system involving a pulsar suggests Einstein was right.
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.
The Vela pulsar makes about 11 complete rotations every second, it also has a glitch.

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.
For the first time, human beings harnessed the power of atomic fission.
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.
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.

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.

They're are the overachievers of the universe: incredibly dense but very small when compared to others stars. So how much do we know about the extreme behaviour of neutron stars?
The strongest magnets in the universe – but how does a magnetar form? (Artist’s impression of magnetar in the cluster Westerlund 1.)
Magnetars are stars that are incredibly dense, rapidly spinning, amazingly hot and – as their name suggests – are the most magnetic objects known in the universe. The magnetic field on the surface of a…
Stars shine, for sure, but PSR J1719-1438 is sporting some serious bling.
A planet has been found in our Milky Way galaxy that may be made entirely of diamond. As reported in Science today, an international astronomy team led by Swinburne University’s Matthew Bailes, has discovered…
