Planets and Asteroids

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.

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?

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?

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.

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.

The asteroid, known as 2024 RW1, is only the ninth to have been spotted before its impact.

Eyewitness video from the northern city of Tuguegarao captured the moment the asteroid passed into the atmosphere. 

Mars may have enough water hiding in the cracks of underground rocks to form a global ocean, new research suggests. The lead scientist on the project says it means some environments could possibly be habitable on the Red Planet. 

It might be chilly, but Australia's night sky puts on a dazzling show at this time of year. Rug up and use our guide to see if you can spot some of our winter wonders.

The James Webb Space Telescope has revealed trace elements of hydrogen sulphide — the chemical compound behind the stench of rotten eggs — on a planet 64 light-years away. 

Two asteroids — including one that's newly-discovered — are passing Earth this week. Here's what to know and how to spot them in the night sky.

Renowned for its multi-million-dollar wedding industry, Queensland's Sunshine Coast hinterland hopes to add stargazing to its tourism drawcard.

In 2016, astronomers published a study suggesting a ninth planet could be hiding on the edge of our Solar System. Eight years later, they're still looking for it. So what will it take to find it?

The new planet, named WASP-193b, appears to dwarf Jupiter in size, yet researchers found it's the second-lightest planet discovered to date.

After this weekend's epic aurora australis display, the Bureau of Meteorology says there is still a geomagnetic storm underway that may produce visible southern lights in parts of Australia but the chance of seeing them is less likely. 

The Earth has experienced its strongest geomagnetic storm of the past 20 years, resulting in stunning light displays across the globe. But what are geomagnetic storms exactly and do they present a risk to people or the planet?

The so-called super-Earth is among the few rocky planets outside our solar system with a significant atmosphere.

The Eta Aquariids are one of two meteor showers caused by leftover debris from Halley's comet, and this year could be a cracker — experts predict up to 21 meteors an hour. 

The helicopter, called Ingenuity, has transmitted its final message to Earth and will now serve as an immobile data-gathering unit on the red planet's surface, the space agency says.

Astronomers have discovered the second-largest black hole known to be in the Milky Way, and it's located just 2,000 light-years from Earth.
