This equipment produces a laser beam (not seen) to create a guide star in the atmosphere. This facility began operating on 28 January 2006, after five years of preparations. By focusing on the artificial guide star, telescopes at the VLT can be calibrated to remove the effects of the atmosphere on observations. This process is known as adaptive optics, and leads to improved observations. Warning signs and goggles protecting against the laser are at lower left. Photographed in November :
