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.
Astronomers in Puerto Rico have picked up signal from a faint star that's not like anything they've seen before.
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.
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.
Very few African universities offer postgraduate degrees in astronomy. This gap in knowledge and training can be addressed through international partnerships and collaboration.
Astronomers are making new discoveries about our galaxy thanks to a more detailed map of the Milky Way.
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.
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.
The Aperture Spherical Radio Telescope could help reveal how the universe evolved.
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.
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.
Something mysterious is pulling our Milky Way through space at a much faster rate than expected. So what could it be?
A technological revolution in astronomical observations could be the key to understanding the perplexing phenonenon known as 'fast radio bursts' from outer space.
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.
Astronomers think they may have found evidence within our galaxy of some of the missing matter thought to make up our universe.
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.
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.
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?
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.
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?
