Your weekly dose of awe: A space-time warp

• The cluster has bent the light of the more distant galaxy, known as the Sunburst Arc, around it, allowing scientists to see it in a way they couldn't have otherwise.
• That warping — called gravitational lensing — has created "12 images of the background galaxy, distributed over four major arcs," seen in this photo, according to NASA.

What they're saying: "The magnification allows Hubble to view structures as small as 520 light-years across that would be too small to see without the turboboost from the lensing effect," NASA said in a statement.
