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:
“From the beach the child holding the hand of her father,
Those burial clouds that lower victorious soon to devour all,
Watching, silently weeps.”
—Walt Whitman (1819–1892)
“Not only does democracy make every man forget his ancestors, but also clouds their view of their descendants and isolates them from their contemporaries. Each man is for ever thrown back on himself alone, and there is danger that he may be shut up in the solitude of his own heart.”
—Alexis de Tocqueville (1805–1859)
“By the road to the contagious hospital
under the surge of the blue
mottled clouds driven from the
northwest—a cold wind.”
—William Carlos Williams (1883–1963)
