The Chinese rover identified hydrated minerals—likely associated with groundwater—in sediments dating to the Red Planet’s most recent geologic period.
Geologically young regions of Pluto’s southern hemisphere were likely resurfaced by cryovolcanism, data from the New Horizons spacecraft reveal.
The discovery, gleaned from observations of volcanoes on four continents, could help constrain models of volcanic eruptions.
The laser-based instruments aboard the GRACE-FO satellites may be extended to other geophysical applications to collect data on other submonthly mass changes in Earth’s system.
Phosphorous stored in watersheds and affects water quality for decades. A new model predicts phosphorus accumulation and depletion, and the consequences for water quality conservation measures.
Little seismic unrest preceded the 2014 eruption of a stratovolcano in Indonesia, which suggests that the eruption was kick-started internally by volatile-triggered overpressure.
Samples returned from the surface of an asteroid show that these small bodies may have more water than previously thought and could have delivered that water to Earth.
Thermal modeling suggests that active magmatism in the past few hundred thousand years could account for the presence of a large lake previously hypothesized beneath the Red Planet’s southern ice cap.
Primordial solar storm conditions are believed to have significantly enhanced the loss of water and other atmospheric volatiles in Mars’ history.
