Mercury, the smallest planet in our solar system and the one closest to the Sun, has long baffled scientists with its twisted, fractured surface. Towering cliffs, deep ridges, and sprawling fracture ...

Mercury is an odd little planet. The closest world to the Sun has some extreme surface structures, steep hills and cliffs, ...

The meteorite Northwest Africa (NWA) 7325 was initially proposed as a possible fragment of Mercury. However, its mineralogy ...

As the closest planet to the Sun, Mercury is exposed to the star's enormous gravitational field. And it's really stressful.

This poorly matches Mercury's estimated surface composition. As a result of this, and other factors, this link has been challenged. Aubrite meteorites have also been proposed as potential ...

Thursday’s flyby was the fourth of six planned around Mercury, with BepiColombo grazing the planet just 103 miles above its surface. The images it sends back from these close encounters, Dr ...

Mercury could have a thick underground layer of diamonds, scientists say. Some of the stones may have found their way to the surface, according to a recent study.

As on most other rocky planets, the water on Mercury probably came from asteroids that crash-landed onto the surface. This water hides in Mercury’s craters, untampered with since primordial times.

Mercury, the solar system’s smallest planet, may have vast riches beneath its surface, according to a stunning discovery by a NASA spacecraft.

From its "absurd" core to the baffling chemical composition of its surface, Mercury is full of surprises – not least the planet's origins. But some answers could be held in rocks found in Cyprus ...

The BepiColombo orbiter completed its third of six planned Mercury flybys, hugging the planet from 150 miles above ground and overcoming the powerful gravitational pull of the sun.
