ESPRESSO spectrograph. Room where light beams coming from the four Very Large Telescope (VLT) Unit Telescopes at the Paranal Observatory, Chile, are brought together and fed into fibres that deliver the light to the ESPRESSO (Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations) spectrograph in another room. ESPRESSO measures changes in the light spectrum with a great sensitivity to search for Earth-size rocky exoplanets. It successfully made its first observations in November 2017. | |
