January 2022	In collaboration with Microlensing Observations in Astrophysics (MOA), OGLE reported the first solidly detected rogue black hole, using microlensing data to measure both light amplification and deflection.
2021	Discovery of OGLE-2019-BLG-0960Lb, another extremely small planetary body with 0.0071 Jupiter masses.
2020	Detection of OGLE-2019-BLG-0551b, a very small planetary body with 0.0242 Jupiter masses.
2018	Discovery of OGLE-2018-BLG-0799Lb, a planet with 0.22 Jupiter masses and an orbital period of 1.75.
2017	Significant year of planet discoveries including OGLE-2016-BLG-1190Lb (a massive 13.38 Jupiter mass planet), OGLE-2016-BLG-1195Lb, OGLE-2013-BLG-0132Lb, OGLE-2013-BLG-1721Lb, and OGLE-2016-BLG-0263Lb.
