Despite the absence of a global Earth-like magnetic dipole, the Martian atmosphere is well protected from the effects of the solar wind on ion escape from the planet. New research shows this using ...

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission has identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet ...

Mars may look calm and barren from afar, but beneath its quiet, dusty red surface lies a surprisingly dynamic atmosphere. Despite having an atmosphere less than 1% as dense as Earth's, the winds on ...

A 6.5-foot Mars sand ridge called Hazyview reveals how strong, steady winds once shaped the planet’s surface and soil ...

Astronomers have detected over 5,800 confirmed exoplanets. One extreme class is ultra-hot Jupiters, of particular interest because they can provide a unique window into planetary atmospheric dynamics.

Particles from Earth’s atmosphere have been carried into space by solar wind and have been landing on the moon for billions of years, mixing into the lunar soil, according to a new study. The research ...
