The goal of this expedition went far beyond collecting sediment cores. Scientists also set out to sample the water stored within the sediments, including from sandy layers that act as […]
The excess abundance of highly siderophile elements (HSEs), as inferred for the terrestrial planets and the Moon, is thought to record a `late veneer’ of impacts after the giant impact […]
We investigate the magnetic signature of oceanic circulation in Ganymede’s subsurface ocean using kinematic induction modeling. Our approach couples zonal jet flows from rotating thermal convection simulations with magnetic field […]
A new study led by researchers at the Earth-Life Science Institute (ELSI) at Institute of Science Tokyo challenges a long-standing assumption about Earth’s most extreme ice ages. Using numerical geochemical […]
This image shows many slope streaks of various orientations at fairly high latitude (for slope streaks).
This photo was selected by public vote and featured as “Image of the Week” for Week 262 (Feb. 15 – 21, 2026) of the Perseverance rover mission on Mars.
A hilly landscape that looks like spiderwebs when viewed from orbit holds clues to the history of water on ancient Mars.
Blood Falls is a unique feature that appears at the snout of the Taylor Glacier in the upper Taylor Valley, East Antarctica.
In the whole history of Earth’s climate, few events are as extreme as those that geologists call “Snowball Earth.”
This scene from the eastern side of Terra Cimmeria, northeast of the Hellas impact basin, shows many impact craters of different sizes and types of preservation, with a few sharp-looking […]
