.... The massive planet, known as MOA-2016-BLG-227Lb, was discovered by the Microlensing Observations in Astrophysics (MOA) collaboration who used gravitational microlensing, a method which replies on light being ‘bent’ by massive objects in between...

... years and getting in the way of the background star. The team found them through their gravitational microlensing effects. Microlensing is an effect that occurs when the gravity of a foreground object causes space-time to bend, magnifying something...
