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 | |
