The image is a photograph of a clear blue sky. The sky is a bright, clear blue with no clouds in sight. In the center of the image, there is a white contrail that appears to be a trail of smoke or vapor. The trail is curved and extends upwards towards the sky. On the right side of the photo, there are trees with bare branches, and a power line can be seen in the foreground. The image is taken from a low angle, looking up at the sky from a window.
