Description
VLT and laser guide under star trails. Time-exposure image of star trails over the Yepun telescope of the Very Large Telescope (VLT) as it shines a laser guide, at the Paranal Observatory, Atacama desert, Chile. This beam creates a guide star in the atmosphere, which is used to calibrate the telescope to remove the effects of the atmosphere on observations, a process known as adaptive optics.
