The moon has shrunk by more than 45 metres in circumference over the last few hundred million years because of its core gradually cooling.
On February 3, 2024, NASA’s Juno spacecraft made a second close flyby of Io, the third largest of Jupiter’s moons. We were able to see a volcunic erruption there like never before.
If life ever existed on Mars, the Perseverance rover’s verification of lake sediments at the base of the Jezero crater reinforces the hope that traces might be found in the crater.
An international team of researchers has gained new insights into the formation of diamond rain on icy planets such as Neptune and Uranus, using the X-ray laser European XFEL in Schenefeld.
ESA's Mars Express has revisited one of Mars's most mysterious features to clarify its composition. Its findings suggest layers of water ice stretching several kilometers below ground—the most water ever found in this part of the planet.
New research shows the early lunar crust which makes up the surface of the Moon was considerably enriched in water more than 4 billion years ago, counter to previously held understanding.
Neptune is fondly known for being a rich blue and Uranus green – but a new study has revealed that the two ice giants are actually far closer in colour than typically thought.
Jupiter's largest moon, Ganymede, features a surprisingly strong magnetic field for its size. Now, a new experimental study has put one of the leading models of core dynamics to the test: the formation of crystalized 'iron snow'.
Japan's SLIM space probe entered the moon's orbit on Monday in a major step towards the country's first successful lunar landing, expected next month.
When researchers reconstructed lava flows on Mars, they realized the red planet is a lot more active than they previously thought.
The picture, resembling a glowing blue marble rippling into a black ocean, was funneled through the telescope’s infrared filters to capture wavelengths future space travelers wouldn’t see with the naked eye.
A study zooms in on data that NASA’s Cassini gathered at Saturn’s icy moon and finds evidence of a key ingredient for life and a supercharged source of energy to fuel it.
On the 14th of December our star unleashed an X-class solar flare. Solar physicists classify strong flares into three categories, with C being the weakest, M the middling group and X the most potent.
The scientists made a startling observation when they observed that the atmosphere of Mars dramatically ballooned outwards because of a void created due to a powerful gust of solar wind.
Water from Earth's surface can find its way deep into the planet, and new research explains how it changes the outermost region of the metallic liquid core.
