The serene Milky Way galaxy towers over Alamut Valley in Iran in this spectacular night sky photo.
Scientists estimate the Milky Way galaxy contains roughly 400 billion stars bound together by gravity. Above the glow of the mountains, the barred spiral galaxy appears as a faint band in the sky. In the image, car headlights can be seen on a winding road in the valley. Lights from nearby cities also reflect within southern horizon clouds.
