GPI Imaging of the Planetary System HR 8799 in K Band, Showing 3 of the 4 Planets

Caption

Planet b is outside the field of view shown here, off to the left. These data were obtained on Nov. 17, 2013 during the first week of operation of GPI and in relatively challenging weather conditions, but with GPI's advanced adaptive optics system and coronagraph the planets can still be clearly seen and their spectra measured.
