Gravitational Lensing Detects Exoplanet
Показать описание
Observations of the star OGLE 2003-BLG-235L showed an increase in brightness which was associated with a stellar and planetary gravitational lens passing in front of it. The mass of the star ad planet passing in front of the background star causes a magnification of the background star, causing it to appear brighter.
