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 ...

Climate change may not expand drylands

Does a warmer climate mean more dry land? For years, researchers projected that drylands—including deserts, savannas and shrublands—will expand as the planet warms, but new research from the Harvard John A. Paulson School ...

Possible detection of hydrazine on Saturn's moon Rhea

In a new report on Science Advances, Mark Elowitz, and a team of scientists in physical sciences, optical physics, planetary science and radiation research in the U.S., U.K., India, and Taiwan, presented the first analysis ...

What caused the ice ages? Tiny ocean fossils offer key evidence

The last million years of Earth history have been characterized by frequent "glacial-interglacial cycles," large swings in climate that are linked to the growing and shrinking of massive, continent-spanning ice sheets. These ...

SOFIA discovers water on sunlit surface of moon

NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, ...

Tiny moon shadows may harbor hidden stores of ice

Hidden pockets of water could be much more common on the surface of the moon than scientists once suspected, according to new research led by the University of Colorado Boulder. In some cases, these tiny patches of ice might ...

Could life exist deep underground on Mars?

Recent science missions and results are bringing the search for life closer to home, and scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA) and the Florida Institute of Technology (FIT) may have figured ...
