A widely used technique to monitor sulfur dioxide was tweaked to focus on water vapor at Peru’s Sabancaya Volcano. Results show that the volcano steamed up prior to its 2016 eruption.
Water-carved valleys may be relatively young, challenging assumptions about the history of the Red Planet's climate.
A new hypothesis might reconcile two opposing theories that have tried to explain Mars's mysterious history for more than 40 years.
Manganese deposits in Gale Crater fractures are similar to Earth features that usually require flowing water and highly oxidizing conditions.
The discovery of dense concentrations of recurring flowlike features in two Valles Marineris chasms could aid in the search for life and influence future exploration of the Red Planet.
New research shows that an electric field surrounding Venus is stripping its atmosphere of water—and the same phenomenon may plague exoplanets scientists hope might be habitable.
The rover's neutron spectroscopy instrument hints at an unexpected trend: The upper soil levels in the layers of Gale Crater's Kimberley formation seem to hold more water-associated hydrogen.
The experiments mimicked cooling of magma at the lunar surface. They found that any water in interior molten rock might have escaped so fast at the surface that none was left to be measured.
New map identifies varying water usage in hydraulic drilling operations across the United States and what this means for potential environmental impacts.
Researchers present maps of hydrogen and sulfur that hint at water locked in hydrous sulfates in Mars's southern hemispheric soil.
