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:
“It is to the press mankind are indebted for having dispelled the clouds which so long encompassed religion, for disclosing her genuine lustre, and disseminating her salutary doctrines.”
—James Madison (1751–1836)
“When I consider the clouds stretched in stupendous masses across the sky, frowning with darkness or glowing with downy light, or gilded with the rays of the setting sun, like the battlements of a city in the heavens, their grandeur appears thrown away on the meanness of my employment; the drapery is altogether too rich for such poor acting. I am hardly worthy to be a suburban dweller outside those walls.”
—Henry David Thoreau (1817–1862)
“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)
