Years ago, when I first heard about the possibility of gravitational
lensing, where a star bends the light around it, I saw a really sloppily
done graphic.  The graphic implied you  would only get two points, left and
right to the star.  I immediately thought there ought to be a ring. The
article I read seemed to confirm that you'd get one image superimposed to
the left and right.   I then assumed there was some property of light or
gravity or magnetism I didn't know about, or the graphic  designer and/or
the article writer didn't know what they were talking about.

They didn't!

They're called Einstein RINGS!
