The image is a photograph of a cloudy sky. The sky is a light grey color and the sun is partially visible in the bottom right corner. In the center of the image, there is a long, thin white line that appears to be a contrail or trail of smoke or vapor. The trail is curved and extends upwards towards the sky. It is likely from an airplane or other aircraft. The image is taken from a low angle, looking up at the sky and the trail.
