Extreme cooling near Arsia Mons may let water vapor form ice particles directly, helping explain Mars’s striking morning ...

Clouds need two essential ingredients to form, and both must be present simultaneously for the process to begin. There are two ingredients needed for clouds to form: water and nuclei. The first ...

Mars Express can capture large stretches of the Martian surface at high resolution. Alongside ESA’s ExoMars Trace Gas Orbiter ...

A new study of the oddest cloud on Mars, which reappears every year at the Arsia Mons volcano, says that "exotic physics" is ...

Clouds form when water vapor—an invisible gas in the atmosphere—sticks to tiny floating particles, such as dust, and turns into liquid water droplets or ice crystals. In a newly published study, we ...

Thousands of tiny particles in the atmosphere unseen by the naked eye scatter and absorb solar radiation and become one of the bases for the formation of clouds. A lot of these particles are not ...

Climate models may underestimate tiny marine aerosol particles that help clouds form, potentially affecting estimates of ...

The researchers concluded that the dominant particles are clouds, not photochemical hazes. Their modeling points to magnesium silicate clouds, a mineral material common in rocky settings, forming high ...
