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:
“The inhabitants of earth behold commonly but the dark and shadowy under side of heaven’s pavement; it is only when seen at a favorable angle in the horizon, morning or evening, that some faint streaks of the rich lining of the clouds are revealed.”
—Henry David Thoreau (1817–1862)
“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)
“Why didst thou promise such a beauteous day,
And make me travel forth without my cloak,
To let base clouds o’ertake me in my way,”
—William Shakespeare (1564–1616)
