The second largest #moon of #jupiter and the third largest moon in the solar system, #callisto is an ancient celestial body. She may contain at least two oceans under her surface. Tidally locked to her #jovian parent, seen in the background (an actual #nasa photograph), Callisto harbors one of the best chances for ancient life. This #artwork captures the moment in the next century that mankind discovers the secrets she harbors. #art #digitalartist #new #dailydoodle #dogs in #space
