Laser Guide Star Facility at the European Southern Observatory's VLT (Very Large Telescope), Cerro Paranal, Chile. The VLT consists of 4 unit telescopes, including this one, named Yepun, and began operating in 2006. The laser (PARSEC) produces this orange beam to create a guide star in the atmosphere. By focusing on the artificial guide star, VLT telescopes are calibrated to remove the effects of the atmosphere on observations, a process known as adaptive optics. The beam is pointing close to the Milky Way, the band of stars crossing the sky.
