Several dwarf galaxies have been discovered close to our own Milky Way and are adding to our understanding of how galaxies form. But why haven’t astronomers seen them before?
In a few billion years, the sun will become a red giant so large that it will engulf our planet. But the Earth will become uninhabitable much sooner than that. After about a billion years the sun will…
As an astronomer, I get a lot of requests for help. “I’d like to buy a telescope,” the conversation usually goes. “Can you give me some tips on what to look for?” Sadly, there’s little advice I can offer…
Two white dwarfs found orbiting each other at the centre of a planetary nebula are now known to have enough mass that they will eventually trigger a special kind of supernova, according to research published…

Meteors have been seen since people first looked at the night sky. They are comprised of small pieces of debris, typically no larger than a grain of dust or sand, which continually crash into the Earth’s…
Astronomers are trying to improve their hunt for rapid bursts of radio emission in the universe called Fast Radio Bursts (FRBs) so they can better observe these mysterious events, which are thought to…

Watching meteors in the night sky can be fun, although typically you only see a few flashes an hour. But there are certain times of the year when you can see many more – events known as meteor showers…
The Theory of Everything is a film about two people who meet at university and fall in love. But what makes it remarkable is that one of them is Professor Stephen Hawking and that when he and Jane Wilde…
The wise men were likely accomplished Greek astrologers, watching the stars for signs of a king’s birth. Technical terms used in the Bible’s description point to a real astronomical event.
Our understanding of gamma ray bursts (GRBs) – flashes of gamma rays from explosions in distant galaxies – since they were discovered more than 50 years ago may not be as solid as first thought. Research…

The best meteor shower of the year should put on an impressive display this weekend – weather permitting – with the annual Geminids poised to light up the sky with bright, long meteors visible as frequently…
Indigenous Australian practices, developed and honed over thousands of years, weave science with storytelling. In this Indigenous science series, we’ll look at different aspects of First Australians’ traditional…
Australia’s Mopra telescope, nestled in NSW’s Warrumbungle National Park, is earmarked for closure in a year thanks to CSIRO funding cuts. But this one-of-a-kind telescope is well worth saving. Few of…
Astronomers have found thousands of exoplanets and the hunt is on for life beyond Earth. Once biological neighbors are identified, our planet’s philosophies and religions will need to adapt.
How many stars can you see at night? Right now people all over the world are being asked to go out and count them! It’s part of a dark-sky awareness campaign that’s been held each October for the past…

A detailed study of comets orbiting the young nearby star Beta Pictoris is published today in the journal Nature, and it reveals striking similarities to the comets found in our solar system. Over the…
Each month, at the time of new moon, the sun and moon are together in the daytime sky. Most of the time the moon passes by unnoticed. But at least twice a year, somewhere on Earth will see the moon pass…

As Earth orbits the sun, it continually ploughs through dust and debris left behind by passing comets and asteroids. On any night of the year, a keen-eyed observer might see five, or even ten, meteors…
