High Quality Content by WIKIPEDIA articles! The Gemini Planet Imager (GPI) is a high contrast imaging instrument being built for the Gemini South Telescope in Chile. The instrument will achieve high contrast at small angular separations, allowing for the direct imaging and integral field spectroscopy of extrasolar planets around nearby stars. The collaboration involved in planning and building the Gemini Planet imager includes Lawrence Livermore National Lab (LLNL), the American Museum of Natural History (AMNH), the Herzberg Institute of Astrophysics, the Jet Propulsion Laboratory, the University of California, Berkeley, the University of California, Los Angeles, the University of California, Santa Cruz, the University of Montreal.
