PICTURE OF THE DAYsee all »

Jupiter and Orion

Above the horizon and clouds, at left, Jupiter is the brightest “star” in this view captured from Los Andenes, in the great night sky of La Palma, Canary Islands. In the center lies the Rosette nebula. Above and to the right is Orion, highlighted by orange Betelgeuse. To create the spikes in the star, the photographer used a star filter in the front of the lens. (Canon 60Da DSLR, 24mm lens at f/2, ISO 1250, 49-second exposure, taken September 30, 2013, at 2:37 a.m. local time, from Los Andenes, Canary Islands)
