Coming in strong, weak and micro varieties, FTP, name this astronomical phenomenon in which light bends around an object due to its mass, frequently resulting in a double image.
In 1924, Orest Chwolson became the first man to describe this effect. Walsh, Carswell and Weymann identified the first example of it in SBS 0957 + 561, a double quasar, which makes sense because mainly quasars are found from the application of this effect. One famous example of it, also named for Huchra, contains four identical components and is called an (*) Einstein cross. Applying this concept to the search for dark matter candidates has confirmed the existence of MACHOs in the Large Magellanic Cloud, and when the lens and observer are in perfect alignment with the source of radiation, an Einstein ring is said to form.
