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:
“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)
“What is green? The grass is green,
With small flowers between.
What is violet? Clouds are violet
In the summer twilight.
What is orange? Why, an orange,
Just an orange!”
—Christina Georgina Rossetti (1830–1894)
“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)
