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:
“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)
“But he her fears to cease
Sent down the meek-eyed Peace;
She, crowned with olive green, came softly sliding
Down through the turning sphere,
His ready harbinger,
With turtle wing the amorous clouds dividing,
And waving wide her myrtle wand,
She strikes a universal peace through sea and land.”
—John Milton (1608–1674)
“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)
