Volcanism has played a more extensive role in shaping the surface of Mercury than scientists had thought. This result comes from multispectral imaging data gathered in January 2008 by MESSENGER, the ...

Mercury has long baffled astronomers because it defies much of what we know about planet formation. A new space mission ...

Researchers have found that several volcanic deposits on Mercury's surface require mantle melting to have started close to the planet's core-mantle boundary, which lies only 400 km below the planets ...

From just 295 kilometers above Mercury's surface, ESA's BepiColombo transfer probe has captured stunning close-up images while on its final flyby of the tiny, sunbaked world. The photos represent a ...

Parts of Mercury’s varied surface came from melted material over 200 miles deep inside the planet near the core-mantle boundary, NASA scientists found. The tiny planet of Mercury, the closest to the ...

If you walked into a home and the kitchen was strewn with dusty old copies of National Geographic, you’d probably wonder where they came from. That’s basically what Mercury looks like. Well, except ...

Mercury has a very diverse surface, with some areas boasting young-looking terrain and others that are heavily cratered, but scientists couldn't explain why the planet's surface had such stark ...

Researchers suspect that two meteorites found in the Sahara Desert in 2023 may originally have come from Mercury, which would make them the first identified fragments of the solar system’s innermost ...

A rare type of meteorite found on Earth may have been a critical ingredient in the geologic recipe that shaped the surface of Mercury, new research shows. An amazing variety of features cover the ...

The long-anticipated BepiColombo mission is entering its decisive phase. Launched in 2018, this joint endeavor between the ...

Mercury has gotten some new wrinkles in its old age. The innermost planet shows signs of relatively recent tectonic activity, a new study suggests. Tiny cliffs on the surface — just tens of meters ...
