gravitational lensing (IMAGE)
Caption
Figure 1: Illustration of gravitational lensing by a galaxy. Light from a more distant and reddish galaxy is bent by a more nearby and bluish galaxy, which acts like a natural cosmic telescope to magnify the more distant galaxy. In this instance, multiple images of the reddish galaxy are created, forming a reddish ring-like feature referred to as an Einstein ring around the bluish galaxy.
