Description
Laser Guide Star Facility at the European Southern Observatory's VLT (Very Large Telescope), Cerro Paranal, Chile. The laser (PARSEC) produces this orange beam to create a guide star in the atmosphere. This facility began operating on 28 January 2006, in the VLT's Yepun telescope (left). 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. Two other VLT telescopes are also seen, along with one of the smaller VLT 1.8-metre auxiliary telescope (rounded dome). Photographed at twilight in March 2009.
