Gamma-ray bursts occur when a massive star explodes or when two neutron stars merge. A newly discovered burst has puzzled astronomers, as it lasted much longer than astronomers would have expected.

The object has a highly unusually long rotation period, and was found in an area we call the neutron star ‘graveyard’.
A mysterious repeating signal from our galactic backyard is a reminder the universe is full of unexpected surprises, if only we should look.
Astronomers watched a pair of pulsars for 16 years to test the theory of general relativity, which has stood unchallenged for over a century.
The discovery of an ancient star in the Milky Way’s halo is providing evidence for another source that would have produced the galaxy’s heavy elements.
The aftermath of a black hole colliding with a neutron star has been recorded on Earth.
Gravitational waves reveal the demise of super-dense neutron stars spiralling into their black hole companions - the first time such strange and exotic star systems have ever been observed.
A small add-on to existing gravitational wave detectors could reveal what happens to matter as it becomes a black hole, a process like the big bang in reverse.
Radio flare may be the result of a giant star orbiting some unusual object – a combination we have never seen before.
When you look at the squiggly lines on Joy Division’s famous album cover, you’re seeing a record of lightning in outer space.
The signal came in on ANZAC Day, ripples in space-time from the merger of two neutron stars an estimated 500-million light years away. But where it happened is still a mystery.
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.
