Editor’s note: when it comes to conducting field trips – sorties – Away Team missions – on another world, astrogeology and astrobiology and astrochemistry overlap with one another all the […]
The meteorite which caused the extinction of the dinosaurs also created an underground environment suited to supporting new life, and new research suggests it lasted for millions of years longer […]
Editor’s note: there are currently two advanced missions heading for the jovian system – Europa Clipper and ESA Juice – to study icy Europa and the other icy worlds orbiting […]
Despite their large abundance, it is still unknown whether and under what conditions rocky planets around M dwarf stars can host atmospheres.
One of the Jupiter Icy Moons Explorer (JUICE) mission goals of the European Space Agency, launched in 2023 April, is the detailed characterization of Ganymede, Jupiter’s largest moon and a […]
Mercury’s polar cold traps host water ice deposits that are likely populated with impact-delivered water via Mercury’s exosphere.
In the region where the ExoMars Rosalind Franklin rover will search for signs of life, clay deposits extend beyond previous estimates, a new study finds. One hypothesis even suggests a […]
The martian atmosphere hosts dynamical phenomena ranging from planet-encircling dust storms to mesoscale orographic clouds and nocturnal low-level jets.
Valles Marineris, like the Grand Canyon in northern Arizona, provides a spectacular look at the geologic history via layered sediments that get older with depth.
Branching deposits in this area have been shown to be consistent with river deltas. Measurements of channel-belt width and thicknesses of river deltas on Earth point to relationships between width, […]
