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:
“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 (1922–1986)
“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)
“A building is akin to dogma; it is insolent, like dogma. Whether or no it is permanent, it claims permanence, like a dogma. People ask why we have no typical architecture of the modern world, like impressionism in painting. Surely it is obviously because we have not enough dogmas; we cannot bear to see anything in the sky that is solid and enduring, anything in the sky that does not change like the clouds of the sky.”
—Gilbert Keith Chesterton (1874–1936)
