To confirm life on other planets, we need to detect far more molecules in their atmospheres than we currently do to rule out non-biological chemical processes.

A rocky planet discovered in the Virgo constellation could change how we look for life in the universe.

An ensemble of twenty-five disk galaxies

UNSW-led research will enable astronomers to look at any galaxy in the Universe and predict when it will stop producing stars.

Starry night sky with tree silhouettes in foreground

A faraway galaxy with almost no dark matter has threatened to break our theory of galaxy formation. New evidence suggests the galaxy isn’t an anomaly – but a victim of theft.

Day and night at the Anglo Australian Telescope

The Australian-led GALAH project has released chemical information for 600,000 stars.

Close-up of solar flare and coronal mass ejection on the Sun

Scientists have trained an artificial intelligence (AI) to help understand the evolution of young stars and their planets – a new benchmark in the use of AI in astronomy.

Planet Venus

The discovery of phosphine in the acidic clouds of Venus can't be explained by any known chemical or geological processes.

Scientists find remnant of strange dismembered star cluster at Galaxy’s edge

South Pole

Stars viewed from a place called Dome A in Antarctica can finally be seen without their twinkle – which means in much greater detail.
