Milky Way and laser guide star at twilight. At right is a laser guide star (green) from the William Herschel Telescope, with the Milky Way at left, just after sunset with the telescopes of the Roque de Los Muchachos observatory. These telescopes are located at an altitude of 2400 metres on La Palma, the Canary Islands, enabling views obscured by clouds for those at lower altitudes. The laser beam is a guide star used in the technique of adaptive optics. Photographed in 2017. | |
