Gravitational Lens Effect

Gravitational Lens Effect
The focusing of light from a distant galaxy or quasar by an intervening galaxy to produce multiple images of the distant body.
Gravitational Red Shift ...

In 1979 the gravitational lens effect predicted by Einstein's General Theory of Relativity was confirmed observationally for the first time with images of the double quasar 0957+561.

One final effect that is worth mentioning is the gravitational lens effect. Light traveling through a strong gravitational field will be bent; basically the light will fall downward just like anything else.

Gravitational microlensing is an astronomicaltechnique used to detect planet - stellar mass objects in space using thegravitational lens effect.

They have been duplicated by the gravitational lens effect of the cluster of yellow, elliptical and spiral galaxies near the photograph's center.

This image shows several blue, loop-shaped objects that are multiple images of the same galaxy, duplicated by the gravitational lens effect of the cluster of yellow galaxies near the middle of the photograph.

The signature of these objects is the occasional amplification of the light from extragalactic stars by the gravitational lens effect.
