One-dimensional models show how the expected variability in radiogenic heat from U and Th in a rocky planet’s mantle could control the presence of a magnetic field and thus habitability.
Mirror-like reflections are typically an indication of liquid, but looks can be deceiving. Today’s paper investigates alternative solutions for bright backscatter from Titan’s tropics.
The apparent paradox of an early warm wet Earth but wimpy young sun may be solved by improved constraints and sophisticated atmospheric models.
Never get lost on Titan again! A global geologic map of Saturn’s largest moon provides an opportunity to review age-old methods that help explain an exciting and active world in our solar system.
Lifeforms like trees cast unique shadows on the Earth’s surface. Understanding this effect may enable remote detection of life on exoplanets.
