Gravitational Lensing: When Gravity Bends Light

Gravitational lensing occurs when the powerful gravity of a massive galaxy or galaxy cluster bends light traveling from a distant object. This effect can create bright arcs, distorted shapes, or multiple images of the same galaxy. Astronomers use gravitational lensing to study distant galaxies, dark matter, and the universe’s structure. #GravitationalLensingGravitySpaceFactsAstronomyUniverseCosmologyDarkMatterDeepSpaceSpaceScienceAmazingUniverse
