Twin Quasar: 1979 Lensed into 2 images The lens is a galaxy known as YGKOW G1: First quasar found with a jet with apparent superluminal motion 3C 279: 1971 [25] [26] [27] First quasar found with the classic double radio-lobe structure 3C 47: 1964 First quasar found to be an X-ray source 3C 273: 1967 [39] First "dustless" quasar found
The object itself was detected in ESO images dating back to 1980, but its identification as a quasar occurred only several decades later. [2]An automated analysis of 2022 data from the European Space Agency's Gaia satellite did not confirm J0529-4351 as too bright to be a quasar, and suggested it was a 16th magnitude star with a 99.98% probability.

“The size of these magnificent creatures was incredible," Fry said in a news release earlier this month. "One female anaconda we encountered measured an astounding 6.3 meters (20.8 feet) long."
A multiple-image quasar is a quasar whose light undergoes gravitational lensing, resulting in double, triple or quadruple images of the same quasar. The first such gravitational lens to be discovered was the double-imaged quasar Q0957+561 (or Twin Quasar) in 1979. [ 75 ]
