Milky Way over coastal trees. The Milky Way (upper centre) is a band of stars and nebulae stretching vertically across the sky. Also visible above the trees is the Summer Triangle, an asterism made from the three brightest stars visible in this part of the sky: Altair, Deneb, and Vega. The glow of town lights is on the horizon at lower left. Photographed in September near Locmariaquer, Brittany, north-western France.
