ESOcast 74: Mapping the Southern Skies
30 April 2015
ESOcast 74 looks at ESO’s pair of survey telescopes at Paranal: the Visible and Infrared Survey Telescope for Astronomy (VISTA) and the VLT Survey Telescope (VST).
These telescopes chart the southern skies in search of the proverbial needle in the haystack: rare astronomical objects, such as hidden star clusters and remote quasars.
Unlike larger telescopes, which examine small areas of the sky in great detail, survey telescopes scan broad areas quickly and efficiently, creating huge archives of valuable data that astronomers can scour for items of interest.
