By systematically assessing data gathered by different methods, researchers refined estimates of global glacier melt and its contribution to sea level rise.

A new study uses inversions of orbital gravity and magnetic field data to argue for the presence of ancient, long-lasting hydrothermal systems on Mars.

Drainage divide migration is influenced by tectonics and climate over long periods. New research in Israel shows that even shorter-term wet-dry cycles can move divides.

New Antarctic ice core data bolster model predictions of ocean heat content during glacials and interglacials.

The Antarctic ice sheet behaves like a non-Newtonian fluid and may be more nonlinear than previously thought. This impacts ...

A new study deepens understanding of magnetic field behavior recently discovered by NASA in Earth’s magnetosphere.

An instrument aboard the Vikram lander suggests that buried water ice could be found at higher latitudes, making it more abundant and easier to extract than previously believed.

A multidisciplinary synthesis of the Campi Flegrei, Italy volcanic setting highlights the importance of sub-caldera layering ...

Under Trump’s first budget draft for NASA, the Nancy Grace Roman Space Telescope, illustrated above, might not launch. Credit: NASA Research & Developments is a blog for brief updates that ...

Cycles of ice sheet growth (glacials) and intervening warmth (interglacials) in Earth’s past—largely triggered by shifts in the amount of solar radiation (insolation) reaching the planet ...
