Mars has an active, electrically charged surface where dust storms and spinning dust devils regularly move and reshape the landscape. Mars is often portrayed as a dry, empty world, but the planet is ...

Researchers uncover how Mars affects Earth’s orbit, offering new insight into the planetary forces behind ice ages.

The engineering lesson is simple: Sometimes the best observatory is the one already parked at another planet. When an interstellar comet was in a viewing geometry that kept Earth-based telescopes too ...

The European Space Agency's ExoMars Trace Gas Orbiter image of interstellar comet 3I/ATLAS as it passed close to Mars. (The European Space Agency) A mysterious interstellar comet — just the third such ...

This summer, scientists spotted an incredibly rare visitor to Earth’s solar system—a comet, now known as 3I/ATLAS, that entered our solar system from the galaxy beyond and is zipping past the sun at a ...

MAVEN was built to last in orbit until 2030 — that's not looking likely anymore.

New simulations show Mars plays a key role in shaping Earth’s long-term climate by influencing its orbit and axial tilt over hundreds of thousands to millions of years.

Solar wind sounds poetic, but it's a very real and powerful phenomenon, connecting the Sun to every part of our solar system.

A mysterious interstellar comet — just the third such object ever confirmed to have entered our solar system — streaked past Mars last week. A spacecraft in orbit around the red planet had a front-row ...
