... [Narrator] 8. This isn’t the only intriguing effect that gravitational lensing can produce. Take these five quasars photographed by Hubble back in 2006. They all look very similar and close together… perhaps a little too similar. In fact, these are not quasar quintuplets, but a single quasar seen fi ...
