Laser Guide Star, Cerro Paranal, Chile. Laser beam being used to create a guide star in the atmosphere. This is the Laser Guide Star Facility (PARSEC) at the European Southern Observatory's Very Large Telescope site in Chile. It began operating on 28 January 2006, after five years of preparations. The aim of the facility is to use the laser to make atoms high in the atmosphere glow, appearing as a faint star in telescopes. This allows the telescopes to be calibrated to remove the effects of the Earth's atmosphere on observations. This process is known as adaptive optics, and leads to improved observations.Restrictions:.
