Twin Quasar
The Twin Quasar (also known as Twin QSO, Double Quasar, SBS 0957+561, TXS 0957+561, Q0957+561 or QSO 0957+561 A/B), was discovered in 1979 and was the first identified gravitationally lensed double quasar, not to be confused with the first detection of light deflection in 1919. It is a quasar that appears as two images, a result from gravitational lensing.
