Gravitational lensing occurs when the gravity of a massive object, like a galaxy, warps the fabric of spacetime, bending the light from a more distant background object.

"They're so rare, and they're incredibly useful scientifically," said Conor O'Riordan of the Max Planck Institute for Astrophysics.
