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 garden flew round with the angel,
The angel flew round with the clouds,
And the clouds flew round and the clouds few round
And the clouds flew round with the clouds.”
—Wallace Stevens (1879–1955)
“One who never turned his back but marched breast forward,
Never doubted clouds would break,
Never dreamed, though right were worsted, wrong would triumph.
Held we fall to rise, are baffled to fight better,
Sleep to wake.”
—Robert Browning (1812–1889)
“Who knows whither the clouds have fled?
In the unscarred heaven they leave no wake,
And the eyes forget the tears they have shed,
The heart forgets its sorrow and ache;
The soul partakes the season’s youth,
And the sulphurous rifts of passion and woe
Lie deep ‘neath a silence pure and smooth,
Like burnt-out craters healed with snow.”
—James Russell Lowell (1819–1891)
