Artificial laser stars at the VLT, time-lapse footage

Référence de la vidéo 12329240
Artificial laser stars at the VLT. Time-lapse footage of the laser beam of an artificial star rising over the Very Large Telescope (VLT) at the Paranal Observatory in Chile's Atacama Desert. The observatory is located on Cerro Paranal at an altitude of 2600 metres. The arid high-altitude desert offers near perfect conditions for observations. However, the atmosphere still distorts light from distant objects. If a suitable reference star to correct for distortions isn't available, a system of lasers allows astronomers to create artificial reference stars, as seen here. The artificial guide stars are used to calibrate the VLT telescopes to remove the effects of the atmosphere on observations, a process known as adaptive optics. Footage published in 2016.
