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:
“A ward, and still in bonds, one day
I stole abroad;
It was high spring, and all the way
Primrosed and hung with shade;
Yet was it frost within,
And surly winds
Blasted my infant buds, and sin
Like clouds eclipsed my mind.”
—Henry Vaughan (1622–1695)
“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)
“My mother, who hates thunderstorms,
Holds up each summer day and shakes
It out suspiciously, lest swarms
Of grape-dark clouds are lurking there....”
—Philip Larkin (1922–1986)
