NASA Announces a Significant Advance in Planet Hunting

Artist's conceptAccording to a NASA press release: "'Planet-hunting astronomers have crossed an important threshold in planet detection, with the discovery of two planets that may be smaller in mass than Saturn. Of the 30 extrasolar planets around Sun-like stars detected previously, all have been the size of Jupiter or larger. The existence of these Saturn-sized candidates suggests that many stars harbor smaller planets, in addition to the Jupiter-sized ones."
