HARPS-N and ESPRESSO

摘要

Meanwhile, the HARPS team and collaborators have made another version of their spectrometer for the northern hemisphere. HARPS-N is fixed to Italy's 3.6-meter Galileo National Telescope in the Canary Islands, which can observe the same patch of sky that Kepler does. The researchers are also designing a next-generation spectrometer called ESPRESSO, which will operate from 2016 at ESO's Very Large Telescope at Cerro Paranal in Chile. VLT is an array of four 8.2-meter scopes; ESPRESSO will be portable enough to attach to whichever has available observing time.
