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 heavens 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 (18171862)
“My mother, who hates thunderstorms,
Holds up each summer day and shakes
It out suspiciously, lest swarms
Of grape-dark clouds are lurking there....”
—Philip Larkin (19221986)
“The gray-eyed morn smiles on the frowning night,
Checkring the eastern clouds with streaks of light,
And fleckled darkness like a drunkard reels
From forth days path and Titans fiery wheels.”
—William Shakespeare (15641616)
