Planetary Surface Processes
How landscapes evolve across worlds near and far
This journey emerged from 40 new research articles across Interdisciplinary, Astronomy & Space and Biology.
This topic surfaced automatically because research activity spiked across multiple disciplines this month.
From the shifting rivers of Earth to the nitrogen glaciers of Pluto, planetary surfaces are constantly reshaped by powerful geological forces. Recent discoveries reveal that volcanism, landslides, and erosion sculpt terrain not just on our home planet, but across the solar system in surprising and often bizarre ways. Understanding these processes helps us decode the dynamic histories written in the landscapes of other worlds.
New observations from rovers, satellites, and deep space missions are revolutionizing our understanding of how planets evolve over billions of years. These discoveries reveal active processes on worlds once thought geologically dead—from Mercury's accelerating shrinkage to methane-destroying volcanic plumes—while advanced remote sensing techniques are uncovering hidden features like subsurface glaciers that reshape our maps of Earth itself.

Open questions
Science still doesn't fully know:
- How do cryovolcanic processes on icy moons compare to silicate volcanism on rocky planets?
- What mechanisms drive the surprisingly rapid shrinkage of Mercury's interior and surface?
- Whether liquid nitrogen glacier flows on Pluto follow the same physics as water-ice glaciers on Earth remains unclear
