Einstein Ring, MG1654+1346, Quasar Radio Lobe

---

Radio ring around galaxy MG1654+1346, the image in the ring is that of a quasar radio lobe, discovered in 1989 by et al. Radio emission was first detected using the NRAO 300ft telescope in Green Bank, west Virginia. In observational astronomy an Einstein ring, also known as an Einstein-Chwolson ring or Chwolson ring, is the deformation of the light from a source (such as a galaxy or star) into a ring through gravitational lensing of the source's light by an object with an extremely large mass (such as another galaxy or a black hole). This occurs when the source, lens, and observer are all aligned. The Einstein Ring image is from VLA observations at 6cm. The ring diameter is 2 arc seconds.
