Software-Processed NICMOS Image of HR 8799 Planetary System
Recent, sophisticated software processing of the NICMOS data removes most of the scattered starlight to reveal three planets orbiting HR 8799. Astronomers used this decade-old image to calculate the orbits of the planets. CreditsNASA, ESA, and R. Soummer (STScI)
