The image shows a clear blue sky with a thin white line in the center. The line appears to be a contrail or trail of some kind, possibly from an airplane or a jet. The contrail is made up of two curved lines that intersect at the top and bottom of the image. The lines are straight and appear to be made of a thin, white material. The sky is a bright, clear blue with no clouds in sight. The image is taken from a low angle, looking up at the contrail.
