The main targets of the experiment are the Magellanic Clouds and the Galactic Bulge , because of the large number of intervening stars that can be used for microlensing during a stellar Transit . Most of the observations have been taken at the Las Campanas Observatory in Chile . Cooperating institutions include Princeton University and the Carnegie Institution . The project has been divided into three phases, OGLE-I, OGLE-II, and the present OGLE-III. OGLE-I was the project pilot phase; for OGLE-II, a Telescope was specially constructed in Poland and shipped to Chile. PLANETS DISCOVERED Nine planets have so far been discovered by the OGLE project. Five of the planets were discovered by the transit method and four by the gravitational microlensing method.
