A giant exomoon hundreds of times the size of Earth is revealing secrets about how giant planets like Jupiter and Saturn formed. They might also help astronomers find planets where life may thrive.
NASA's Europa Clipper mission just got the green light - here's what it could achieve.
Although the rings of Saturn may look like a permanent fixture of the planet, they are ever-changing. New analyses of the rings reveal how and when they were made, from what and whether they'll last.
Whether anything could live in Europa's subsurface ocean depends on what kind of salt it contains. Now scientists have found out.
The Great Red Spot has remained an essentially constant feature of Jupiter's turbulent atmosphere for at least the past several hundred years. How can a storm persist for so long?
The five planets visible to the naked eye since ancient times are putting on a dazzling display this month, in a night-sky dance along with the Moon.
Jupiter's bands are one of its most striking features – and can be seen from Earth – but they only go so deep within the giant planet. Now scientists think they know why.
Jupiter now has at least 79 moons, the most for any known planet. But where did these newly discovered moons come from?
All five five planets visible to the naked-eye are on show in the night skies over Australia, and a Blood Moon on the way too.
We could find evidence of life on Europa within a couple of decades.
Now's a great time to see Jupiter as it's about to be the closest to Earth for some time. Time too to catch up with the latest on the Juno mission, exploring the largest planet in our Solar System.
Surprising new results from the Juno mission may us help work out what's going on at Saturn and other gas giants, too.
New experimental results on methane may help us to uncover whether Uranus really is the coldest planet.
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.
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.
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.
Measurements suggest Jupiter's core may be fluffy rather than dense and that its magnetic field is much stronger than previously thought.
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?
There has been much excitement this week about the possibility of water -- and life -- on some newly discovered exoplanets. But we can look closer to home for evidence of ET.
