Unusual Space Photo of the Day - Gravitational Lensing

Today's space photo shows an object with an unusual shape, which can be explained by a process called gravitational lensing. This process causes light from far away to be bent and pulled by the gravity of an object between the source and the observer. In this case, the light from the background galaxy has been distorted by the gravity of the galaxy cluster sitting in front of it. Gravitational lensing proves that gravity isn't a force, but rather a consequence of space and time being warped by mass.
