(Optical Gravitational Lensing Experiment)
(survey searching for microlensing transients)

OGLE (for Optical Gravitational Lensing Experiment) is an astronomical survey that aims to study dark matter by looking for gravitational microlensing during transits of stars. It surveys regions likely to have transits such as the galactic bulge, Large Magellanic Cloud and Small Magellanic Cloud. The survey began in 1992 and continues, with phases numbered OGLE-I, II, III, and currently, IV.

As a bonus, it has uncovered extra-solar planets by the microlensing technique.
