The seven most extreme planets ever discovered
Researchers recently discovered the hottest planet known. But which one is the coldest? And the biggest?
How we managed what Einstein thought was impossible – and used his theory to weigh a star
Astronomers report the first ever measurement of light bending around a star other than our own.
A new discovery of gravitational waves has black holes in a spin
Scientists have made a third detection of gravitational waves, again caused by the merger of two black holes. But they think there's something different about the black holes in this case.
LIGO detects more gravitational waves, from even more ancient and distant black hole collisions
These ripples in the very fabric of the universe were hypothesized by Einstein a century ago. Now scientists have detected them for the third time in a year and a half – ushering in a new era in astrophysics.
African scientists are punching above their weight and changing the world
Africa's overall contribution to research might be small, but smart people are undertaking smart and important work on and about the continent.
ASKAP telescope speeds up the hunt for new Fast Radio Bursts
It used to take weeks to find any of these mysterious signals from deep in space but when the new telescope started looking it found one within days. Then another.
Physicists use Einstein’s ‘spooky’ entanglement to invent super-sensitive gravitational wave detector
Einstein called entanglement "spooky action at a distance”. But now it's been used to design an incredibly sensitive detection method for gravitational waves.
The other Eurovision star hunt: Australia joins with Europe to explore the universe
Australia's new partnership with the European Southern Observatory will give our astronomers access to much bigger telescopes.
Why data-driven science is more than just a buzzword
Science today is increasingly data-driven, but our education system has not caught up.
Curious Kids: What plants could grow in the Goldilocks zone of space?
Plants on other planets are bound to be even weirder than the strangest ones we find on Earth – if they even exist.
Curious Kids: Does space go on forever?
People used to think that when they looked up at the night sky, they were seeing all of space. Then American astronomer Edwin Hubble found out something so amazing, NASA named a telescope after him.
Water, weather, new worlds: Cassini mission revealed Saturn’s secrets
With the probe now on its 'Grand Finale,' a Cassini team member describes the amazing discoveries it made about the ringed planet and its many moons.
Our discovery of a minor planet beyond Neptune shows there might not be a ‘Planet Nine’ after all
It turns out that a common physical process called diffusion can explain the orbits of faraway minor planets – no need for a Planet Nine.
Live fast, die young: a massive ‘dead red’ galaxy seen for the first time in the early Universe
The recipe book for galaxy formation may need to be rewritten after the discovery of a massive galaxy that stopped making new stars early in the Universe's history.
Kindred skies: ancient Greeks and Aboriginal Australians saw constellations in common
Many of the constellations we know in the night sky come from myths of the ancient Greeks. But similar stories are told by the oldest living cultures on Earth, including those of Australia.
Exoplanet discovery by an amateur astronomer shows the power of citizen science
A Darwin mechanic's success in the hunt for new exoplanets shows how amateur and professional scientists can work together on new research.
Stargazing citizens and scientists share the hunger to find Planet 9
To help find Planet 9, you just need a computer and a little astronomy knowledge. Already, 120,000 images have been processed by citizen scientists in just 3 days.
Aliens, very strange universes and Brexit – Martin Rees Q&A
The Astronomer Royal answers some of the world's – and the universe's – biggest questions.
Something big exploded in a galaxy far, far away: what was it?
A burst of gamma rays in a distant part of the universe reveals the birth of another black hole.
