The Canon 5200mm super telephoto lens may be the world's largest camera lens, but it's no match for lenses the size of an entire galaxy, so massive that they deform the light of objects behind them. They're called gravitational lenses.
The galaxy cluster at the center of this image has so much gravitational force that it warps and distorts our view of everything behind it. This photo offers a particularly dramatic example: look at that twisted galaxy on the right.
Gravitational lenses are cosmic phenomena that radically distort light passing by, make objects behind the lens appear much brighter, and help astronomers see distant parts of the universe. And now we've seen a quasar get in on the fun.
