New measurements by NASA’s New Horizons spacecraft show higher than model-predicted levels of interstellar dust as the spacecraft approaches the putative outer edge of the Kuiper Belt.
For a quiet, dusty lump of a planet we see today, Mars has had a surprisingly violent history, one that could reveal some clues about Earth.
Scientists identified water on two main-belt asteroids, 7 Iris and 20 Massalia, using data from the now-defunct SOFIA airborne observatory.
Scientists have discovered that a pair of rings circling an asteroid-like chunk of rock in the cold reaches of space out past Jupiter are likely being shepherded by a tiny, unseen moonlet.
On new recently released NASA images show the moons of Saturn in all their glory, as if they came straight out of the pages of science fiction.
NASA scientists are just getting started in their analysis of fragments brought back from the Bennu asteroid, and the early indications are that the material it contains originated from an ancient ocean world.
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.
