NASA’s Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars 20 years ago. In this image, the bluish glow in the sky above the Sun would be visible to us if we were there, but an artifact of the panoramic camera’s infrared imaging capabilities is that with this filter combination, the redness of the sky farther from the sunset is exaggerated compared to the daytime colors of the Martian sky.
