Researchers used ice core data to reconstruct seasonal temperatures throughout the Holocene. The results link especially hot summers with patterns in Earth’s orbit.
Callisto’s H Corona: Offspring of the Surface or the Atmosphere?
The mostly unknown Callisto’s H corona is created by a global tenuous H2 atmosphere and not by surface water as previously believed, providing the first evidence for H2 in Callisto’s atmosphere.
Tracing the Path of Gas Atoms from Earth to the Final Frontier
Scientists capture the first complete image of Earth’s luminous geocorona and prove its ecliptic north–south symmetry.
Water Beneath the Surface of Mars, Bound Up in Sulfates
Researchers present maps of hydrogen and sulfur that hint at water locked in hydrous sulfates in Mars's southern hemispheric soil.
