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:
“These are the clouds about the fallen sun,
The majesty that shuts his burning eye:
The weak lay hand on what the strong has done,
Till that be tumbled that was lifted high
And discord follow upon unison....”
—William Butler Yeats (1865–1939)
“The gray-eyed morn smiles on the frowning night,
Check’ring the eastern clouds with streaks of light,
And fleckled darkness like a drunkard reels
From forth day’s path and Titan’s fiery wheels.”
—William Shakespeare (1564–1616)
“Ah, Hope! what would life be, stripped of thy encouraging smiles, that teach us to look behind the dark clouds of to-day, for the golden beams that are to gild the morrow.”
—Susanna Moodie (1803–1885)
