WISE J224607.57-052635.0 is an Extremely Luminous Infrared Galaxy (ELIRG) which, in 2015, was announced as the most luminous galaxy in the Universe. The brightness is 300 trillion times that of the Sun (349×1012L☉[1]). The light is generated by a quasar 10 billion times the mass of the Sun. The light emitted by the quasar is converted to infrared rays by dust. The galaxy releases 10,000 times more energy than the Milky Way galaxy, although smaller. It has a light travel distance of 12.5 billion light-years. The galaxy was discovered by using the Wide-field Infrared Survey Explorer.[
