Two new papers from members of the MESSENGER Science Team provide global-scale maps of Mercury’s surface chemistry that reveal previously unrecognized geochemical terranes large regions that have ...

The chemical composition of a planetary body reflects its starting conditions modified by numerous processes during its formation and geological evolution. Measurements by X-ray, gamma-ray, and ...

ANN ARBOR, Mich.–By measuring the charged particles in the planet Mercury’s magnetic field, a University of Michigan sensor enabled the first observations about the surface and atmospheric composition ...

Images taken by NASA's Messenger spacecraft and released in the probe's final days use colour to reveal the mineral composition of Mercury's surface. Michelle Starr is CNET's science editor, and she ...

Mercury, the blazingly hot little world at the inner edge of our solar system, largely remains the enigma it has always been. That’s mostly because it’s 88-day solar orbit makes it so tough to reach.

Two new papers from members of the MESSENGER Science Team provide global-scale maps of Mercury's surface chemistry that reveal previously unrecognized geochemical terranes—large regions that have ...

Scientists have created global-scale maps of Mercury's surface chemistry that reveal previously unrecognized geochemical terranes -- large regions that have compositions distinct from their ...
