Artistic impression of life on a world that does not spin, so that it is tidally-locked. The parent star does not rise or set and one side of the planet faces the same side to the star. This scenario shows a planet with a thick atmosphere near a stable red dwarf. On the side facing the star, air warms and migrates to the far, dark side where it cools, causing perpetual wind. In this scenario, there are mountain ranges out of sight, and this protects an area for life to evolve. Perhaps it has seasons of sorts, so these plants have a short spell to grow as quickly as possible before the storms return again. Illustration.
