What happens when matter is squashed to the brink of collapse? We weighed a neutron star to help NASA find out
Neutron stars contain some of the universe’s most exotic states of matter – but there’s no easy way to peek inside.
A strange intermittent radio signal from space has astronomers puzzled
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.
We saw one of the most powerful magnets in the Universe come to life – and our theories can’t quite explain it
Astronomers caught the bizarre ‘awakening’ of an incredibly rare magnetic star.
We went looking for glowing interstellar gas – and stumbled on 49 unknown galaxies
An attempt to study gas in one galaxy with the MeerKAT radio telescope detected 49 other galaxies instead.
Astronomers finally caught radio waves from 40 large galaxies in the nearby universe
Do all big black holes in very massive galaxies emit radio waves? We used the latest radio telescopes to find out.
We traced a powerful radio signal to the most distant source yet – a galaxy billions of lightyears away
A record-breaking discovery of an extreme ‘fast radio burst’ opens a window into the early universe.
Starlink satellites are 'leaking' signals that interfere with our most sensitive radio telescopes
Starlink satellites emit bright, unintended and unexpected signals that can be detected by radio telescopes.
Astronomers have discovered a rare 'polar ring galaxy' wrapped in a huge ribbon of hydrogen
New ASKAP images reveal a giant hydrogen ring around the spiral galaxy NGC 4632.
A mysterious interstellar radio signal has been blinking on and off every 22 minutes for over 30 years
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.
