What is the “Molten Ring” that Hubble saw? – Salon
Astronomers say the Molten Ring is a terrific example of an “Einstein ring,” caused by gravitational lensing

On December 14th, Hubble Space Telescope officials revealed striking images of an astronomical phenomenon called the “Molten Ring.” The object, which appears as a golden arc stretched across a dense cluster of stars, is one of the largest and most complete Einstein rings ever discovered in our universe.
Named for the physicist, an Einstein ring appears when, due to a process called gravitational lensing, light from a galaxy is diverted by a massive object en route to Earth. If the observer, lens,…
