The Swiss win out in the discovery of the planet, or rather the proving that it is actually there. They studied it for no less than four years to make sure that the planet does in fact exist. They analyzed the data received from the High Accuracy Radial velocity Planet Searcher (HARPS) instrument in Chile. HARPS is a 3.6 meter telescope that is more able to accurately detect exo-planets not only like Saturn but those that are less massive. Planets like Uranus and smaller masses can be detected through both the much more sensitive instrument HARP and the method it uses of checking for stellar wobbles. The method is far from new but with the lens being constantly adjusted we are better able to search for smaller earth-like planets.
So as time goes on between the Alpha Centauri star system and the many planets Keppler has found, it seems Science Fiction will be leading the way moving out to Deep Space.
