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:
“Well, thus we play the fools with the time, and the spirits of
the wise sit in the clouds and mock us.”
—William Shakespeare (1564–1616)
“Fogs and clouds which conceal the overshadowing mountains lend the breadth of the plains to mountain vales. Even the small-featured country acquires some grandeur in stormy weather when clouds are seen drifting between the beholder and the neighboring hills.”
—Henry David Thoreau (1817–1862)
“Put the staff in my hands; for I go to the Fenians, O cleric, to chaunt
The war-songs that roused them of old; they will rise, making clouds with their breath,
Innumerable, singing, exultant; the clay underneath them shall pant,
And demons be broken in pieces, and trampled beneath them in death.”
—William Butler Yeats (1865–1939)
