ESPRESSO

ESPRESSO

ESPRESSO is a new third-generation, high-resolution, fiber-fed and cross-dispersed echelle spectrograph for the visible wavelength range, for the European Southern Observatory's Very Large Telescope . Its main feature is the spectroscopic stability and the radial velocity precision. With its very high spectroscopic precision, it will be able to detect Earth-like planets. For example, our Earth induces a radial-velocity variation of 9 cm/s on our Sun. ESPRESSO will build on the foundations laid by the hugely successful High Accuracy Radial Velocity Planet Searcher instrument at the 3.6-metre telescope at ESO’s La Silla Observatory. ESPRESSO will benefit not only ...
