Curiosity travels through ancient glaciers on Mars

3,500 million years ago the Martian crater Gale, through which the NASA rover Curiosity is currently traversing, was covered with glaciers, mainly over its central mound. Very cold liquid water also flowed through its rivers ...

Study finds earlier peak for Spain's glaciers

The last glacial maximum was a time when Earth's far northern and far southern latitudes were largely covered in ice sheets and sea levels were low. Over much of the planet, glaciers were at their greatest extent roughly ...

Melting polar ice could release old viruses

In 1999, Russian scientists famously dug a long-dead frozen woolly mammoth out of the Siberian permafrost. Other things lurking in the frozen earth may be more alive - and more dangerous. Scientists warn that global warming ...

Nereidum Montes helps unlock Mars' glacial past

(Phys.org)—On 6 June, the high-resolution stereo camera on ESA's Mars Express revisited the Argyre basin as featured in our October release, but this time aiming at Nereidum Montes, some 380 km northeast of Hooke crater.

Deep ocean sediment gives ancient temperature record

Scientists have created a more accurate history of how Earth's climate has varied over the last 1.5 million years, after developing a new method that lets them draw on natural temperature records that have never before been ...

New map reveals giant fjords beneath East Antarctic ice sheet

Scientists from the U.S., U.K. and Australia have used ice-penetrating radar to create the first high- resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, an immense ice-buried ...

Geologists Study Historic Patterns of Climate Change

(PhysOrg.com) -- University of Cincinnati geologist Tom Lowell is part of a team studying the effects of melting ancient glaciers. The research has implications for global warming, as published this week in Science Express.

Under Andean ice, a golden prize
