J-PAS (Javalambre Physics of the accelerating universe Astronomical Survey) is an astronomical facility located in Pico del Buitre in Sierra de Javalambre, near Teruel, in Spain. It is constituted of two telescopes: a 2.5-metre primary mirror telescope (T250) and an 80-centimeter telescope (T80). The T250 will observe the sky in 56 colors with a large field 1.2 Giga-pixel camera, constituted by an array of 14 CCDs. J-PAS will observe more than 8000 square degrees (about 1/5 of the whole sky) during 5/6 years. J-PAS filters cover the entire visible region of the electromagnetic spectrum (3500 Å to 10000 Å).
