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.

Holds up each summer day and shakes
It out suspiciously, lest swarms
Of grape-dark clouds are lurking there....”

Or thinly veil the heaven’s mysterious face;
When in some river, overhung with green,
The waving moon and trembling leaves are seen;”
