Geoscientists discover an overlooked source for Earth's water

Where did Earth's global ocean come from? A team of Arizona State University geoscientists led by Peter Buseck, Regents' Professor in ASU's School of Earth and Space Exploration (SESE) and School of Molecular Sciences, has ...

Research team discovers third type of volcanic eruption

(Phys.org)—A team of researchers from New Zealand's Victoria University has discovered what its members believe to be, a third type of volcanic eruption. In their paper published in the journal Nature Geoscience, they describe ...

Magnesium oxide: From Earth to super-Earth

The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors. New work from a team led by ...

Water on the moon: It's been there all along

Traces of water have been detected within the crystalline structure of mineral samples from the lunar highland upper crust obtained during the Apollo missions, according to a University of Michigan researcher and his colleagues.

Scientists to Io: Your volcanoes are in the wrong place

(Phys.org) —Jupiter's moon Io is the most volcanically active world in the Solar System, with hundreds of volcanoes, some erupting lava fountains up to 250 miles high. However, concentrations of volcanic activity are significantly ...

The more we learn about Mercury, the weirder it seems

For such a tiny planet, Mercury is a pretty big puzzle for researchers. NASA's MESSENGER probe already has revealed that the planet is surprisingly rich in elements that easily evaporate from the surface, such as sulphur, ...

Phenomenon of plate tectonics explained

Transform faults subdivide the mid-ocean ridge into segments. Up until now, it was thought that these faults were ruptures that formed in less stable crust areas. Taras Gerya has recorded a model of the dynamics that lead ...
