HR 8799 bcde Beta Pic b

GJ 504 b HD 95086 b

Directly imaged planetary systems

Fomalhaut b

GPI installed on the telescope October 31 2013

“First Light” November 11-17 2013

GPI operated smoothly right out of the box – “best Gemini 1st light ever”Science verification concentrated on known exoplanets

AO first light: November 11 2013

Integral Field Spectrograph (UCLA) produces a spectrum of every pixel

The future

• GPI currently ~8 times more sensitive than existing AO

• Servicing January-Feb. 2014– Mechanisms– Vibration

• Public data release Feb. 2014• Extended commissioning

March-May 2014– Public science verification April 2014

• Large-scale exoplanet survey begins second half of 2014
