The Gemini Planet Imager (GPI) is a next generation adaptive optics instrument being built for the Gemini Observatory. This is an ambitious project with the goal of directly imaging extrasolar planets orbiting nearby stars. The instrument is currently being integrated at the University of California at Santa Cruz.
