How do you work out if a signal from space is a message from aliens?
Astronomers in Puerto Rico have picked up signal from a faint star that's not like anything they've seen before.
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.
The Australian Square Kilometre Array Pathfinder finally hits the big-data highway
After months of running in test-mode, the Australian Square Kilometre Array Pathfinder telescope is now gathering data at an incredible rate to give us a new look at how our universe works.
From rural Kenya to a PhD in astronomy: how partnerships made it possible
Very few African universities offer postgraduate degrees in astronomy. This gap in knowledge and training can be addressed through international partnerships and collaboration.
Under the Milky Way: what a new map reveals about our galaxy
Astronomers are making new discoveries about our galaxy thanks to a more detailed map of the Milky Way.
Radio galaxies: the mysterious, secretive “beasts” of the Universe
It's difficult to get jets - powerful, lightning fast particles - to give up their secrets. The new Square Kilometre Array radio telescope could hold the key to solving jets' mysteries.
Africa’s MeerKAT ‘first light’ images have blown all expectations
What's particularly exciting about "first light" images from South Africa's MeerKAT radio telescope is that they prove Africa is a rising star in the world of astronomy.
China completes world’s largest radio telescope – raising hopes of finding new worlds and alien life
The Aperture Spherical Radio Telescope could help reveal how the universe evolved.
How CSIRO is turbocharging the world’s largest radio telescopes
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.
How citizen scientists discovered a giant cluster of galaxies
The find by citizen scientists of at least 40 galaxies in a cluster more than a billion light years away is the astronomical equivalent of finding a needle in a haystack.
Explainer: what is the Great Attractor and its pull on our galaxy?
Something mysterious is pulling our Milky Way through space at a much faster rate than expected. So what could it be?
Message from aliens or colliding objects? The hunt for enigmatic radio bursts is about to get real
A technological revolution in astronomical observations could be the key to understanding the perplexing phenonenon known as 'fast radio bursts' from outer space.
Tuning in to cosmic radio from the dawn of time
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.
Mysterious blobs in our Milky Way could be part of the missing matter
Astronomers think they may have found evidence within our galaxy of some of the missing matter thought to make up our universe.
Darkness is disappearing and that’s bad news for astronomy
Darkness is precious to astronomers, but it's also good for everybody. We should ensure we preserve the dark by using the latest technologies responsibly.
Cold light: astronomers go to the ends of the Earth to see cosmic carbon
Astronomers have built a new observatory in the cold dry air of a high plateau in Antarctica to peer through our atmosphere and observe carbon in our galaxy.
Scientists turn to crowdfunding to save Australia’s space research from cutbacks
When government funding is cut from science and research in Australia, there are other ways to try to draw money from the public's purse?
What is the search for extraterrestrial intelligence actually looking for?
Given Earth is our sole example of life in the universe, it's hard to know what we're looking for elsewhere in the cosmos.
Why the $100m alien listening project may be a huge waste of time
Simple mathematics suggests that if there are aliens out there, they should have reached us by now. So is it really worthwhile trying to communicate with them?
