            "description": "Because scientists can't see dark matter directly, they have found other ways to investigate it. We can use indirect ways to study things, like looking at a shadow and making an educated guess about what's casting the shadow. One way scientists indirectly study dark matter is by using gravitational lensing.<br><br>Light going through a gravitational lens is similar to light going through an optical lens: It gets bent. When light from distant stars passes through a galaxy or cluster, the gravity of the matter present in the galaxy or cluster causes the light to bend. As a result, the light looks like it is coming from somewhere else rather than from its actual origin. The amount of bending helps scientists learn about the dark matter present.",

It is the largest and one of the most complete Einstein rings ever discovered.This object’s unusual shape is the result of gravitational lensing.  Albert Einstein, in his general theory of relativity, first theorised that a large gravitational field could act as a lens.  For more information, visit https://nasa.gov/hubble.
