A weird cloud forms on Mars each year and now we know why

Astronomers have identified the formation of a unique cloud near Mars's Arsia Mons volcano, attributed to high levels of water vapor in the atmosphere. This phenomenon, previously deemed impossible due to dust levels, is now understood through simulations that replicate the cloud's features via homogeneous nucleation. Researchers suggest that Mars can experience supersaturation, allowing for the cloud's distinctive long tail and outburst pattern, challenging previous assumptions about Martian atmospheric conditions.
