The image is a photograph of a clear blue sky. The sky is a light shade of blue and there are no clouds visible. In the center of the image, there is a thin white line that appears to be a contrail or trail of light. The line is slightly curved and is slightly darker than the rest of the sky. On the right side of the line, there are two small red dots that appear to be stars or planets. The image is taken from a low angle, looking up at the sky and the contrail.
