Airglow Sky over France
Explanation: This unusual sky was both familiar and unfamiliar. The photographer's mission was to capture the arch of the familiar central band of our
Milky Way Galaxy over a picturesque
medieval manor. The surprise was that on this January evening, the foreground sky was found
glowing in a beautiful but unfamiliar manner. The striped bands are called
airglow and they result from air high in
Earth's atmosphere being excited by the Sun's light and
emitting a faint light of its own. The bands cross the entire sky -- their curved
appearance is due to the extremely wide angle of the camera lens. In the foreground lies
Château de Losse in southwest
France. Other familiar
sky delights dot the distant background including the bright white star
Sirius, the orange planet
Mars, the blue
Pleiades star cluster, the red
California Nebula, and, on the far right, the extended
Andromeda Galaxy. The initial mission was also successful: across the top of the frame is the
arching band of our
Milky Way.
