The laying of antennas at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory, is a big job for one of the biggest-ever scientific endeavours.

If there are aliens out there, we'll find them. That's the message from the team behind one of the world's biggest science projects being built in remote Australia.

The European Space Agency's Hera will travel to the scene of the crash and investigate whether the asteroid has a new crater or new shape and whether it has begun to tumble.

Dr Rebecca Allen discusses the Hera mission that seeks to understand the impact on an asteroid that NASA knocked off course in 2022. 

Astrophotographers in Australia have had a field day over the last week, with Comet Tsuchinshan-ATLAS travelling at nearly 300,000 kilometres per hour lighting up our skies.

Described as one of the brightest comets in recent years, it could return looking even more impressive later this month if it survives a close call with the sun.

Scientists have spent more than 1000 nights at the Siding Spring Observatory in an effort to map hundreds of thousands of stars in the NSW sky. 

A telescope in western NSW maps stars in the Milky Way.

It's hoped the data collected using the Anglo-Australian Telescope near Coonabarabran will help scientists test theories about space and how our galaxy was formed.

Three Australians have been in space. Polar explorer Eric Philips is about to become the fourth — thanks to a cryptocurrency entrepreneur.

High in the Chilean desert, the Extremely Large Telescope is taking shape. It promises sharper views of space than we've ever seen — but will Australian astronomers be able to use it?

Comet C/2023 A3 (Tsuchinshan-ATLAS) is bright enough to be seen in the early morning sky with just your eyes. But only if you know when and where to look.

A small asteroid may become a "mini-moon" of Earth's for a couple of months, according to some astronomers. But what makes something a mini-moon, and why are they so hard to spot?

From country to country, keen stargazers have diligently captured the September harvest supermoon.

With NASA's crewed mission to the moon only a year away, first results from radiation experiments onboard Artemis 1 suggest short trips are within human limits, but longer missions or travel to Mars may be challenging.

Get outside just as the sun is going down this evening to see the supermoon rising above the horizon.

The harvest supermoon will be at its biggest and brightest tonight but it's bad news for those in Australia hoping to catch a partial lunar eclipse too.

Robert Towers has made the biggest contribution ever to the South Australian museum's meteor collection, and he has his own unique way of celebrating his finds

For Robert Towers, hunting meteorites is a "wonderful hobby" — but his strike rate is impressive, and he hopes the ancient space rocks could hold undiscovered clues to the origins of the Earth and life itself.

An awe-inspiring image of the progression of Bailey's beads during the 2023 annular solar eclipse has placed first out of 3,500 entries from 58 countries.
