Welcome to a place of vision and beauty. Welcome to the world of space art.
The Sun is situated below the horizon and the only sources of light that illuminate the smooth and white surface of Europa at this time are Jupiter and Io. The light appears to be somewhat bluish to the human eye, as it happens here on Earth with the moonlight, due to the Purkinje effect: When the luminance level is reduced, our vision changes progressively from photopic (cone cells, full color) to mesopic and finally scotopic (rod cells, black and white) and the last colors we perceive are those of short wavelength. The surface of Europa is very reflective. It has an albedo of 0.64, one of the highest in the Solar System.
