ESOcast 141 Light: ESPRESSO — the Next Generation Planet Hunter
The Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations (ESPRESSO) successfully made its first observations in November 2017. Installed on ESO’s Very Large Telescope (VLT) in Chile, ESPRESSO will search for exoplanets with unprecedented precision by looking at the miniscule changes in the properties of light coming from their host stars.
