The HARPS-N (acronym for High Accuracy Radial velocity Planet Searcher for the Northern hemisphere) spectrograph is a high-precision radial-velocity instrument, similar to HARPS on the ESO's 3.6m telescope in Chile. It is installed at the Italian 3.58m Telescopio Nazionale Galileo telescope on La Palma Island (Canary Islands). It allows for planetary research in the northern sky which hosts the Cygnus and Lyra constellations. In particular it allows for detailed follow up research to Kepler mission planet candidates, which are located in the Cygnus constellation region.

The main scientific rationale of HARPS-N is the characterization and discovery of terrestrial planets by combining transits and Doppler measurements.

The HARPS-N Project is a collaboration between the astronomical observatory of the Geneva University (lead), the Center for Astrophysics in Cambridge (Massachusetts), the Universities of St. Andrews and Edinburgh, the Queen's University of Belfast, the UK Astronomy Technology Centre and the Italian Istituto Nazionale di Astrofisica (INAF).

First light on sky[edit]

First light on sky was obtained by HARPS-N on March 27, 2012 and official operations started on August 1, 2012.[1]
