The image is a photograph of a clear blue sky. In the center of the image, there is a long, straight line that appears to be a contrail or trail of light. The line is made up of two parallel lines, one on top and one on the bottom. The lines are slightly curved and appear to be slightly overlapping each other. The sky is a bright, clear blue with no clouds in sight. The image is taken from a low angle, looking up at the line.
