 Fanaroff–Riley classification

The Fanaroff-Riley classification is a classification scheme for radio galaxies, which categorizes them based on their radio morphology and the properties of their radio emission. Introduced by scientists Paul Fanaroff and Julia Riley in 1974, the classification divides radio galaxies into two main categories: **Fanaroff-Riley Type I (FR I)** and **Fanaroff-Riley Type II (FR II)**.
