When was the first observation of gravitational lensing made?
Quick Answer
The first observed gravitational lensing effect was reported in 1979.
The Full Story
The first gravitational lensing system was reported in 1979, when astronomers found two nearly identical images of a distant quasar, later known as the Twin Quasar. The effect occurs when a massive object bends light from a more distant source, as predicted by Einstein's general relativity. This observation provided a dramatic astronomical confirmation of the theory. Gravitational lensing is now widely used to study dark matter and distant galaxies.
