A new kind of "mini rover" moves in could go places that other wheeled rovers couldn't, such as up a sandy hill.

Tiny nanocardboard probes that weigh less than a fruit fly could levitate through the Martian skies to gather data.

The exoplanet Fomalhaut-b likely never was, say astronomers. Their work suggests an expanding cloud of dust instead.

Saturn is far from the sun, so why is its upper atmosphere so hot? Astronomers may have finally solved "one of the great mysteries of planetary science."

New research digs into the red planet's past to figure out where water on Mars actually came from.

"We don't only look at other planets to know what's out there. It's also a way for us to learn things about the planet that's under our own feet."

NASA's Insight mission to Mars is giving researchers a closer look at the planet and its "marsquakes," researchers say.

The Habitable-zone Planet Finder has confirmed the existence of an exoplanet that is likely close in size to Neptune, only 100 light years from Earth.

The proto-Earth formed surprisingly quickly, new research shows. The finding ups the chance of finding water and life on other planets.

Exoplanet NGTS-10b is either "in the last stages of its life, or somehow it's able to live here longer than it should."
