Super-Jupiter mass planet found in the galactic bulge
... planets orbiting beyond the snowline around relatively faint host stars, such as brown dwarfs or M dwarfs. Nonetheless, microlensing is dependent on rare and random events like the passing of one star precisely in front of another, as seen from...

Researchers discover "invisible" stars too dim to be seen
... 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...
