Summary

Story summary

French scientists modeled the Arsia Mons elongated cloud on Mars for the first time.
The cloud extends more than 1,000 miles, comparable to the New York-to-Kansas City distance.
Researchers suggest homogeneous nucleation formed ice crystals without dust particles.
Formation required a 30 °C temperature drop in ten minutes and extreme humidity.
Winds hitting the 65,000-foot Arsia Mons volcano generated a wave that rapidly lifted moist air.
