This is one of my favorite videos on the web: A timelapse video of the Very Large Telescope (VLT) in Chile, a site consisting mainly of four 8.2m telescopes used to probe the cosmos.
The technology that goes into these things is quite remarkable, it goes without saying that we’ve come a long way since Galileo first turned his eye to to sky. These modern telescopes, perched high atop rural mountains, serve as our window to the universe. If you’re wondering what the lasers are, that would be the adaptive optics system. The laser is used as an “artificial star” to correct for atmospheric distortion.
