Einstein ring  

Définition

  • An Einstein ring, also known as an Einstein–Chwolson ring or Chwolson ring (named for Orest Chwolson), is created when light from a galaxy or star passes by a massive object en route to the Earth. Due to gravitational lensing, the light is diverted, making it seem to come from different places. If source, lens, and observer are all in perfect alignment, the light appears as a ring. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Einstein_ring)
