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:
“In such a night, when passing clouds give place,
Or thinly veil the heaven’s mysterious face;
When in some river, overhung with green,
The waving moon and trembling leaves are seen;”
—Anne Finch, Countess Of Winchilsea (1661–1720)
“But he her fears to cease
Sent down the meek-eyed Peace;
She, crowned with olive green, came softly sliding
Down through the turning sphere,
His ready harbinger,
With turtle wing the amorous clouds dividing,
And waving wide her myrtle wand,
She strikes a universal peace through sea and land.”
—John Milton (1608–1674)
“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)
