A recurring 1,800 km-long water ice cloud on Mars, known as the Arsia Mons Elongated Cloud (AMEC), forms daily via 'homogeneous nucleation,' a process previously only theoretical. Published in Nature Geoscience on Oct. 7, the study shows this exotic physics explains the cloud's rapid formation and evaporation, challenging standard models of cloud formation in planetary atmospheres.
ESA's Mars Express image captures Mamers Valles, a vast Martian valley system in the planet's northern hemisphere, where about 30 dust devils appear as small yellow dots with pink shadows. Dust devils on Mars are powerful indicators of wind and help scientists map atmospheric dynamics for future missions. The Mamers Valles region links Mars' ancient southern highlands to its northern lowlands and sits near former glaciers, making it a prime area for studying Mars' past and planning exploration.
