The ‘oldest known nova’ (a star explosion) in the sky was actually not a nova, astronomers show.

We are in the Milky Way. If you travelled on an extremely fast spaceship for more than two million years, you would reach our neighbour, the Andromeda galaxy. All other galaxies are even further away.
People long assumed all the elements we see now were created during the Big Bang. But on May 2, 1952, an astronomer reported spotting new elements coming from an old star and changed our origin story.
Detailed information about stars in our galaxy could help us discover new exoplanets.
Pulsars are rapidly rotating neutron stars and some of them are know to have a “glitch”, and astronomers have captured one as it hapened.
Signals from the first stars to form in the universe have been picked up by a table-sized detector in a west Australian desert. The find also hints at an early interaction with dark matter.
New radio technology has managed to detect the first light in the universe.
On a clear night you can see thousands of stars in the night sky, and there are billions more in our galaxy alone. But are the official star names really up for sale?
Four star names from Aboriginal Australia have been recognised by the International Astronomical Union. So what are they and where to find them?
The precious metal is literally extra-terrestrial, produced in the heart of the stars. How and under what conditions? Scientists know more thanks to a double astrophysical observation.
A guide to meteor showers – what to look out for and when.
Technology has redefined astronomy. Pioneering telescope designs have allowed astronomers to unravel ever more complex questions about the universe and its mysteries.
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.
The gravitational wave itself is the least exciting part of the announcement from LIGO and Virgo. Observing this new source answers many longstanding questions.
How exactly do the stars twinkle in the night sky? As it turns out, the answer is full of hot air… and cold air.
What caused the Big Bang is still a mystery. And that’s just one of the many unanswered questions, in spite of everything we do know about the birth of the Universe.
Australia’s new partnership with the European Southern Observatory will give our astronomers access to much bigger telescopes.
New research shows the insects use the brightness of different stars to work out which direction to go.
A burst of gamma rays in a distant part of the universe reveals the birth of another black hole.
Understanding how the billions of stars in our galaxy formed and evolved is the subject of a huge galactic archaeology project.
