Paul Kalas was the leader of the team who managed the long-sought feat of actually taking a photograph of a planet orbiting another star. Before this, all the planets outside our solar system were found by indirect means. He describes how they achieved the breakthrough, using the Hubble Space Telescope, and discusses the wide range of planets out there that astronomers are discovering.
