Solar System

The BepiColombo probe's flybys of Mercury have revealed just how sharply and rapidly the planet's local environment changes in response to the solar wind.

China's Chang'e 4 rover Yutu 2 has been working on the far side of the moon for nearly six years. It was designed to operate for just three lunar days, or about three Earth months.

A low-density, weak-gravity region has been found below Olympus Mons and the Tharsis volcanoes, while Mars' northern hemisphere is littered with puzzling high-gravity structures beneath the surface.

Earth may have had a Saturn-like ring system long ago, created from the debris of a passing asteroid that our planet tore apart.

Scientists at NASA's Jet Propulsion Laboratory have recreated spider-like araneiform terrain, a geologic formation found on Mars, in a lab on Earth.

The most comprehensive map of clouds on Mars includes a variety of cloud patterns, including some that are unlike anything seen on Earth.

NASA's Curiosity rover has captured a spectacular sight from the surface of Mars: The first-ever photo of Earth alongside the Red Planet's moon Phobos.

Earth will grab itself another moon this month, but only briefly. The "mini-moon" in the form of asteroid 2024 PT5 will stick around for just two months.

Newly released images of Mars reveal a "smiley" salt deposit on the Red Planet's surface. A related study suggests that similar deposits, which were left behind from ancient lakes, may be a good place to look for signs of former life on Mars.
