Check out this nice video about the European Extremely Large Telescope made by Brady Haran (he of the excellent Sixty Symbols videos).I like that it gives informal background and history, away from the usual PR efforts. I was lucky enough to visit Paranal for a few days & nights myself last year while working on the GRAVITY instrument for the VLT Interferometer. Here’s what I wrote back then. But I never got to drive around the desert all the way to Armazones. Very cool.
