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:
“O suns and skies and clouds of June,
And flowers of June together,
Ye cannot rival for one hour
October’s bright blue weather.”
—Helen Hunt Jackson (1830–1885)
“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)
“Put the staff in my hands; for I go to the Fenians, O cleric, to chaunt
The war-songs that roused them of old; they will rise, making clouds with their breath,
Innumerable, singing, exultant; the clay underneath them shall pant,
And demons be broken in pieces, and trampled beneath them in death.”
—William Butler Yeats (1865–1939)
