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.
We may need to re-think our models of Jupiter’s formation thanks to the first results from Juno probe orbiting the planet, and new observations from Earth.
The planet is more similar to Earth than any other – except when it comes to supporting life.
There remain many mysteries that are beyond science. Does that mean that a God truly exists? A scholar gives reasons for this possibility.
JAXA has announced a mission to visit the two moons of Mars and return a rock sample to Earth.
With the probe now on its 'Grand Finale,' a Cassini team member describes the amazing discoveries it made about the ringed planet and its many moons.
Earth is a relatively dry planet compared to some of the other ocean worlds in our Solar system. Life needs water so what about life on these other places?
To help find Planet 9, you just need a computer and a little astronomy knowledge. Already, 120,000 images have been processed by citizen scientists in just 3 days.
A group of astronomers are trying to reclassify Pluto as full 'planet'. But there are good reasons to leave our classification system alone, and this doesn't mean Pluto is any less interesting.
The moon may be slightly older than previously thought, suggests a new study.
Full moons are good reason to look up – and the one on Nov. 14 is no exception. But here’s why you likely won’t see something shockingly different from other full moons you've observed over the years.
Sonification is a technique for converting data into sound. It could transform the study of distant worlds.
Large asteroid hits on Earth have the potential to wipe out humanity so knowing how to detect and deflect them is vital. But we know very little about the interior make up of many asteroids.
What's the best way to find out how people will cope with the journey to Mars and life on another planet? Lock a test crew up for a year in a simulation right here on Earth.
