The VLT and VST

All four of the VLT's Unit Telescopes can be seen in this image, as well as the VLT Survey Telescope (far right). Whereas the VLT is designed to examine small areas of the sky in tremendous detail, the VST surveys large swathes of the sky in a much shorter period of time, collecting a huge archive of data that can be used to find small, interesting objects, such as near-Earth asteroids, exoplanets, and distant quasars.
