News that Venus may harbor life has swept the globe. So how do we find out for sure? A planetary scientist explains what's next.
The discovery of phosphine in the acidic clouds of Venus can't be explained by any known chemical or geological processes.
Two new coins released by the Royal Australian Mint celebrate Indigenous astronomers, who have used the stars to map changing seasons, inform the behaviours of plants and animals, and encode Law.
Supercomputing, frequent flying and powering up observatories: astronomy has an enormous carbon footprint.
COVID-19 may have messed up school and shut down a lot of entertainment venues. But you can still brighten things up by doing a little stargazing at night, an astronomer says.
A small asteroid will cross Earth's orbit on November 2. Scientists aren't sure if the two will collide – but even if they do, there's still no cause for alarm.
Neowise has an orbit of almost 6800 years, meaning that the last generation of people to see it would have lived during the 5th millennium BC.
Astronomers have discovered that stars like the Sun produce huge amounts of lithium late in their lives.
When it comes to commercial space tourism, suborbital flight are the first frontier. But what are the risks? Are there health requirements? What should you know before taking such a way-out trip?
The primary objective of CHEOPS is to better understand the planets that we’ve already found. And its mission is now in full swing.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.
When the outlook is dark, astronomy can help us take the long view and build for the future.
SpaceX recently launched 60 satellites into orbit around Earth as part of its Starlink programme.
Like a cosmic butterfly in the sky, radio galaxy PKS 2014-55 was observed by CSIRO researchers with the Australian SKA Pathfinder telescope.
It is a pretty spectacular achievement to not only rendezvous with an asteroid as it is whizzing around the Sun but also collect a sample. Here's what the researchers learned.
The term 'Big Bang' might make you think of a massive explosion. Put the thought out of your head. Rather than an explosion, it was the start of everything in the universe.
From the Moon's size to the first calculator, the ancients made some jawdropping discoveries without modern technology.
Thirty years ago the Hubble Space Telescope began snapping photos of distant stars, providing a time machine that has taken astronomers back to when the universe was less than a billion years old.
We asked astronomers: are we alone in the Universe? The answer was surprisingly consistent.
