Neutron stars contain some of the universe’s most exotic states of matter – but there’s no easy way to peek inside.

A slowly flickering source of radio waves that changes over time might be a neutron star or a white dwarf – but its behaviour doesn’t quite fit any of our theories.
It’s too heavy to be a neutron star and too light to be a black hole. So what is it?
Astronomers have detected a long-running source of slow, repeating radio pulses that can’t be explained by current theories – but it’s probably not aliens.
By timing radio pulses from an array of galactic pulsars, scientists see hints of gravitational waves from supermassive black hole pairs in a breakthrough that may reveal hidden details of galaxy evolution.
A glowing blob in the sky known as “the cocoon” may be caused by pulsars in the Sagittarius dwarf galaxy.
The pulsar PSR J0523-7125 is more than ten times brighter than any other radio pulsar outside the Milky Way.
Astronomers watched a pair of pulsars for 16 years to test the theory of general relativity, which has stood unchallenged for over a century.
After six decades during which it tracked lunar missions, spotted distant pulsars and quasars, and even expanded our concept of the size of the Universe, the Parkes telescope is still going strong.
Fluctuating radio waves that appear to come from near the heart of the Milky Way are a new puzzle for astronomers.
The Arecibo radio telescope has collapsed but its amazing discoveries will live on.
One of Einstein’s weirder predictions is that massive, spinning objects exert a drag on space-time itself. Now an orbiting pair of unusual stars has revealed this effect in action.
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 little-known Rossi X-ray Timing Explorer spacecraft was like a Geiger counter for the universe, listening to black holes and zombie stars.
Pulsars are rapidly rotating neutron stars and some of them are know to have a “glitch”, and astronomers have captured one as it hapened.
Studying mysterious neutron stars could uncover the secrets of exotic physics – and a way to navigate the stars.
You can’t just buy a radio telescope receiver off the shelf. So CSIRO has been hard at work building receivers for the world’s largest telescopes using the very latest technology.
The Murchison Widefield Array sits in remote Western Australia far from noisy civilisation so it can help us understand the universe by tuning into radio waves from the distant cosmos.
A new study has failed to find evidence of gravitational waves, but that doesn’t mean Einstein was wrong about their existence.
Telescopes have come a long way since the days when they were all about lone astronomers watching the night sky through their upstairs windows. Today teams of astrophysicists build and use much more modern…
