Mars has been a popular destination since space exploration began – and there are plenty of people who’d love to go there.
Nearby planets can affect how one planet ‘wobbles’ on its spin axis, which contributes to seasons.

You might hate winter, but at least you know what to expect every year. Other planets have wobbly axes that lead to wild, unpredictable seasons.
This is how we are used to seeing Uranus and Neptune, respectively. But the colours aren’t accurate.

It turns out Uranus actually changes colour throughout the year.
A Japanese spacecraft is expected to reach Martian orbit in 2025 to collect material from the surface of the moon Phobos before returning to Earth by 2029.
Sixty years ago, philosopher Hannah Arendt argued an interplanetary perspective may be bad news for humanity as we know it.
Uranus is the coldest planet in the solar system.
Five of the Uranus moons might be ocean worlds − and if there’s water, there might be life.
The pieces of Libyan desert glass that formed the basis of the study.
Libyan desert glass originated from the impact of a meteorite on the Earth’s surface.

Viral headlines would have you think Saturn’s rings will vanish in just 18 months. Here’s what that really means and why you don’t need to worry.
Mining an asteroid probably won’t look exactly like mining does on Earth, but some principles will stay the same.

Upcoming NASA missions will help scientists understand the composition of asteroids – which could inform companies one day hoping to commercially mine asteroids.

A distant lump of space rock may have a surprising amount in common with the core of our own planet.

Studying the sample could help answer how water arrived on Earth and how life started.

The asteroid is interesting from a scientific perspective as well as a commercial one.

Controlled experiments are impossible in astronomy, as are direct measurements of physical properties of objects outside our solar system. So how do astronomers know so much about them?
NASA’s OSIRIS-REx mission has delivered pieces of asteroid Bennu, which scientists hope will offer a window into the early era of the Solar System billions of years ago.
Is there life beyond our world?
Planetary analogues are sites on Earth that are so extreme that they replicate those of celestial bodies in our solar system.

A new study of the meteorite Erg Chech 002 makes it one of the most precisely dated space objects and changes our understanding of how elements were spread around the cloud of dust that formed the Sun and planets.

Liftoff to the distant asteroid is scheduled for Oct. 5, 2023 – the beginning of a six-year journey to one of the most unusual objects in the solar system.

The Voyager 2 spacecraft is 20 billion kilometres away and has lost track of Earth. A radio dish near Canberra is the only channel for re-establishing communication.
