The HARPS-N spectrograph is the northern copy of its successful twin, the high-precision radial-velocity instrument HARPS on the 3.6-m ESO telescope in Chile. HARPS-N is located and operated at the italian Telescopio Nazionale Galileo (TNG) on the Roque de los Muchachos observatory (La Palma, Canary Islands). Its main purpose is to perform radial-velocity follow-up of Kepler planet candidates and to search for low-mass extra-solar planets in the habitable zone of their parent stars.

The HARPS-N Project is a collaboration between the Astronomical Observatory of the Geneva University (lead institute), the CfA in Cambridge, the Universities of St. Andrews and Edinburgh, the Queens University of Belfast and the TNG (INAF). The instrument started its operation on August 1st, 2012.
