ESPRESSO, which stands for Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations, is a highly advanced instrument designed for the detection and characterization of exoplanets. Mounted on the Very Large Telescope (VLT) operated by the European Southern Observatory (ESO) in Chile, ESPRESSO is capable of measuring the tiny wobbles in starlight caused by the gravitational pull of orbiting planets. This state-of-the-art spectrograph improves upon its predecessors by combining the light-collecting power of all four of the VLT’s 8-meter telescopes, allowing for unprecedented precision in observing distant stars. ESPRESSO’s capabilities are instrumental in studying Earth-like planets in the habitable zones of their stars, offering insights into their atmospheres and potential for supporting life.
