chorus: Clouds on Mars, photographed by Mars Express, 20th December 2005.
Around 70°S 192°E on the southern Terra Sirenum; this composite is about 50 by 75km. Charlier Crater is partially seen at top. The clouds might be dust picked from the dark region below, but I’m not sure.
Composite of 8 images: 3 (red, green, and blue light) for colour, and 5 monochromatic (ish) in sequence for motion. The colours are probably more suggestive than naturalistic.

is that a giant sheet of acid?
The deepest cave in the world, the Krubera-voronya cave, is the only known cave to exceed a depth of 2000 meters, and we still don’t know how deep it is!
In 2004 it was explored to a depth of 2080 meters which was as far as explorers could go as it was filled with water below, but then in 2012 a diver managed to extend the known depth of the cave to 2197 meters!
