Jupiter swallowed a super-Earth - space - 11 August 2010 - New Scientist: "JUPITER might have secured its position as the solar system's mightiest planet by killing an up-and-coming rival, new simulations suggest. The work could explain why the planet has a relatively small heart, and paints a grisly picture of the early solar system, where massive, rocky 'super-Earths' were snuffed out before they could grow into gas giants."
