Sometimes our deepest views of the universe are the most indirect.
The intrigue: This photo, taken by the Hubble Space Telescope, shows a galaxy about 11 billion light-years away whose image has been distorted and magnified by a massive galaxy cluster 4.6 billion light-years away.
- 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.
