Oexe Leonov's Orbital Sunrise

A curved band mixing black and blue represents the portion of the earth visible due to the rising sun. An then above the earth, a narrow curvature of red, then yellow and then the black of space. And in the centre of the drawing, we see the red sphere of the sun almost risen behind the curvature of the earth. It says something to me that the first art made by humans from outside of earth's atmosphere depicts earth's atmosphere.
