Gravitational Lensing

(focusing electromagnetic radiation by gravitational force)

Gravitational Lensing is the focusing of Electromagnetic Radiation (EMR) by a massive body. The setup is called a Gravitation Lens. A Galaxy has the mass to lens a more distant galaxy or Quasar (QSO).

Gravitational Microlensing is the gravitational effect on electromagnetic radiation by a smaller body such as a star.
