WebRelated to strong lensing, gravitational microlensing events occur when a compact foreground object passes directly in front of a distant object. Microlensing causes the brightness of the background object to briefly increase. ... During its ten-year survey of the night sky, it is anticipated that LSST will detect over 10,000 microlensing ... WebMicrolensing is unique in its capability to rapidly survey the population of cold planets, with a sensitivity to planetary mass that goes down to just below the mass of the Earth. The population of stars that it surveys are low-mass stars, typically M-dwarfs, between here and the centre of the Galaxy. Other methods are capable of detecting ...
