2 June 2016 Astronomy Now

This unusual phenomenon, predicted by Einstein’s theory of General Relativity, was discovered by chance by doctoral student Margherita Bettinelli at the Instituto de Astrof√≠sica de Canarias while analysing images of the Sculptor dwarf galaxy. The “Canarias Einstein ring” is one of the most symmetrical discovered until now and is almost circular.
