Bridge to the Night

In a late July night of Sweden, stars return to the night sky after weeks of bright polar nights. The long exposure image through a fisheye lens has captured star trails over a 100-year old railway bridge over Dal River near Gysinge. The strange illumination on the right (north) are night-shining clouds known as the Noctilucent clouds or NLCs. They lie near the edge of space, reflecting sunlight from about 80 kilometers above Earth's surface. They are usually spotted above the Polar Regions in summer. P-M Heden,
