UT interior in action with MUSE

The interior of Yepun, Unit Telescope 4 (UT4), part of ESO’s Very Large Telescope (VLT), captured in this fish-eye/fulldome time-lapse during the ESO Ultra High Definition Expedition.

Shown here is the Multi Unit Spectroscopic Explorer (MUSE) – a second generation instrument, an innovative 3D spectrograph with a wide field of view, providing simultaneous spectra of numerous adjacent regions in the sky. Such spectrographs are efficient explorers of the Universe in three dimensions (two for the sky positions, and one for the wavelengths). Poised to become a unique and powerful tool for discovering objects that cannot be found in imaging surveys, MUSE, which is based on a number of technological developments, is bringing these advantages to a level never achieved before.
