^[1] The Cloverleaf Quasar is a gravitational-ally lensed quasar which contains a substantial dust content. This also infers that the quasar contains a large amount of gas as well. The gravitational field of at least one if not more foreground galaxies was bent in such a way that it magnified the light from the quasar to produce more than one image. This magnification can be the result of the X-rays in this quasar coming from a small section of its black hole and the optical light comes from a different area. This phenomenon of bending light in order to detect astronomical objects is called gravitational microlensing ^[2] AjBongiorno (talk) 16:19, 5 December 2016 (UTC)
