Planets and Observatory in Twilight

Morning breaks on the Roque de Los Muchachos observatory, on La Palma, Canary Islands. The ecliptic is marked by three planets and the Moon (near the twin heads, Castor & Pollux in Gemini). Venus is in the center, Jupiter is right at the tip of a MAGIC telescope and fainter Mars is directly above Jupiter. The pair of 17-meter multi-mirrored telescopes observe gamma rays indirectly by detecting brief flashes of optical light, called Cherenkov light. On the far back the William Herschel Telescope is beaming a green laser to high atmosphere for its adaptive optics system that aims to remove atmospheric blurring from star images.
