a phenomenon called gravitational microlensing. "Microlensing occurs when three objects—an observer on Earth, a source of light, and a lens—virtually ideally align in space," says Prof.

Gravitational microlensing occurs when one star passes directly in front of a background star, as seen from Earth. The gravitational field of the foreground star acts like a lens, magnifying the ...

PRIME uses wide field imaging and gravitational microlensing techniques that measure brightness variations of faint objects in the infrared spectrum (not visible to humans). To detect exoplanets ...
