Clouds
Mars' dust storms can kick up fine particles in the atmosphere around which clouds can form. These clouds can form very high up, up to 100 km (62 mi) above the planet. The clouds are very faint and can only be seen reflecting sunlight against the darkness of the night sky. In that respect, they look similar to the mesospheric clouds, also known as noctilucent clouds on Earth, which occur about 80 km (50 mi) above our planet.

Famous quotes containing the word clouds:
“From the beach the child holding the hand of her father,
Those burial clouds that lower victorious soon to devour all,
Watching, silently weeps.”
—Walt Whitman (1819–1892)
“Draw up the dew. Swell with pacific violence.
Take shape in silence. Grow as the clouds grew.
Beautiful brood the cornlands, and you are heavy;
Leafy the boughs—they also hide big fruit.”
—Cecil Day Lewis (1904–1972)
“Heaven has its business and earth has its business: those are two separate things. Heaven, that’s the angels’ pasture; they are happy; they don’t have to fret about food and drink. And you can be sure that they have black angels to do the heavy work like laundering the clouds or sweeping the rain and cleaning the sun after a storm, while the white angels sing like nightingales all day long or blow in those little trumpets like they show in the pictures we see in church.”
—Jacques Roumain (1907–1945)
