Artist's Concept of Exoplanet HR 8799b Caption This is an artistic illustration of the giant planet HR 8799b. The planet was first discovered in 2007 at the Gemini North observatory. It was identified in the NICMOS archival data in a follow-up search of NICMOS archival data to see if Hubble had also serendipitously imaged it. Credits NASA, ESA, and G. Bacon (STScI)
