Videos illustrating the technology of telescopes and scientific instrumentation

On this page you will find videos that focus on the technology of telescopes and measuring instruments such as cameras and spectrographs. Among them are lectures, interviews and technical presentations.

Computer-generated view of the Extremely Large Telescope (ELT) of the European Southern Observatory on a mountain summit in Chile’s Atacama Desert. The large, modern telescope with an open dome stands on a flat platform. In the background stretch the barren mountains under a clear sky, faintly lit by twilight. In the foreground, a winding road leads up to the observatory. Logos of several research institutes are visible in the upper left corner. At the bottom of the image, the text ‘Das Extremely Large Telescope (ELT)’ is displayed.
