Caption

Light from the distant quasar 7.9 billion light-years away is bent and magnified in this schematic view by the foreground galaxy's mass 4.6 billion light-years away in a phenomenon called 'gravitational lensing.' Sight lines toward images A and B probe different magnetic fields and gas conditions through different parts of the lensing galaxy.
