Exiled exoplanet likely kicked out of star's neighborhood

The Gemini Planet Imager and the Hubble Space Telescope have revealed details of an unusual exoplanet and its star that suggest the planetary system underwent a violent episode in its early history that ejected the planet to a distance equivalent to 16 times the Earth-Pluto distance and roiled the comet belt closer to the star. This resembles what many people think happened in our solar system's past.
