Amazing - only 1% of the matter causing the lensing distortion is even VISIBLE. Dark matter is not merely "stuff we can't see", but seems to be comprised of particles we don't yet recognize or detect. Yet it comprises most of the structure of the Universe.

Spiral galaxy lensing a quasar into 4 images. The galaxy is NOT near the quasar.
Cosmic mirages!

seen to warp space Gravitational lenses are interesting and their existence a fairly recent addition to our knowledge; but, over on the other thread the National Radio observatory has used the phenomenon to measure the speed of gravity. Catch that?
