Could the hidden seas of icy moons occasionally boil beneath kilometers of ice? Recent modeling suggests that, given just the ...

What can craters on Mars teach scientists about the Red Planet’s climate history? This is what a recent study published in Geology hopes to address as a team of researchers investigated ice buildup ...

Earth's climate has swung between ice ages and warmer periods for millions of years, driven by subtle changes in our planet's ...

ESA’s Rosetta spacecraft has provided evidence for a daily water-ice cycle on and near the surface of comets. Comets are celestial bodies comprising a mixture of dust and ices, which they periodically ...

At the end of Taylor Glacier in Antarctica, a hypersaline brine known as “Blood Falls” flows onto the surface. The red color is from iron oxide. Mineral deposits formed in the past from such fluids ...

Nearly 10,000 years ago, Earth came out of its most recent ice age. Vast, icy swaths of land around the poles thawed, melting the glaciers that had covered them for nearly 100,000 years. Why, after ...

Satellite images from NASA’s Earth Observatory have captured a concerning trend in Antarctica: sea ice reaching its third-lowest maximum on record. Despite the region’s typical seasonal fluctuations, ...
