(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 show 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.
