A new trajectory means the mission to uncover core facts about the asteroid belt will happen sooner than planned.
Having discovered an asteroid from outside the solar system for the first time, scientists are hoping there are more out there – illuminating the path to extrasolar worlds.
A solitary planet in an eccentric orbit around an ancient star may help astronomers understand exactly how such planetary systems are formed.
Astronomers have detected what is believed to be the first interstellar object ever seen passing through our solar system.
The mystery object seen moving through our Solar system shows the void between the stars is far from empty. So can we expect more interstellar visitors?
They erupted for billions of years and make Earth's volcanoes look like molehills. Here's what we know and what we don't know about them.
The last signals from Cassini space probe before it burns up in Saturn's atmosphere will tracked by the Canberra Deep Space Communication Complex.
The Cassini space probe discovered liquid lakes, poisonous gases and the basic elements of life on Saturn's moon, Titan.
The Cassini space probe took us up close and through the beautiful rings of Saturn. It captured some amazing images, and even the sound of the rings during its mission.
The Cassini space probe discovered several new moons on its mission to Saturn, and revealed fresh views of the moons we already knew about.
With only days to go before NASA's Cassini space probe ends its two-decade mission to explore Saturn, what has it revealed about the ringed planet, the second largest in our solar system?
While we on Earth are familiar with our own star, the Sun, the European Space Agency's PLATO mission will explore solar systems similar to ours as well as those that are more exotic.
Ten new remote cameras will soon be scouring the British night skies for meteorites.
The Voyager space probes sent back some amazing images of the planets in the outer Solar System, and they're still talking to Earth every day via Australia's tracking station.
An astronomer explains how and why – and when – eclipses happen, what we can learn from them, and what they would look like if you were standing on the moon.
In five or seven billion years time, the Sun's life will come to an end. And it will be really spectacular - if you're watching from far enough away.
The images are in from the Juno probe's closest flyby so far of Jupiter's Great Red Spot. Citizen scientists are now getting involved in processing those images.
Juno has flown closer to the solar system's most famous storm than any other spacecraft to take the most detailed images to date. They may help scientists reveal some of the spot's best-kept secrets.
You may even be able to find other planets around the star closest to our solar system.
We could learn a lot from any mission to send people to Mars, such as whether there's life elsewhere in the universe or even the technology for new household appliances.
