Sunset on Mars
Cool photo, courtesy of NASA. No relevance to evolution, though, in all likelihood.
On May 19, 2005, NASA's Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera mosaic was taken around 6:07 in the evening of the rover's 489th Martian day, or sol.With apologies to Curiosity.
