Deep diamonds contain evidence of deep-Earth recycling processes

Diamonds that formed deep in the Earth's mantle contain evidence of chemical reactions that occurred on the seafloor. Probing these gems can help geoscientists understand how material is exchanged between the planet's surface ...

New evidence for oceans of water deep in the Earth

Researchers from Northwestern University and the University of New Mexico report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form—the ingredients for ...

Water-rich gem points to vast 'oceans' beneath the Earth

A University of Alberta diamond scientist has found the first terrestrial sample of a water-rich gem that yields new evidence about the existence of large volumes of water deep beneath the Earth.

13 light years away: Earth-like planets are right next door

Using publicly available data from NASA's Kepler space telescope, astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) have found that six percent of red dwarf stars have habitable, Earth-sized planets. Since ...

Recalculating the distance to interstellar space

(PhysOrg.com) -- Scientists analyzing recent data from NASA's Voyager and Cassini spacecraft have calculated that Voyager 1 could cross over into the frontier of interstellar space at any time and much earlier than previously ...

The science behind the life and times of the Earth's salt flats

Researchers at the University of Massachusetts Amherst and the University of Alaska Anchorage are the first to characterize two different types of surface water in the hyperarid salars—or salt flats—that contain much ...

'Superdeep' diamond deepens our understanding of plate tectonics

A unique combination of minerals trapped inside a "superdeep" diamond that originated hundreds of kilometers beneath Earth's surface sheds new light on plate tectonics, the geological processes that give rise to mountains, ...
