final data release for 2MASS occurred in 2003, and is served by the Infrared Science Archive. The goals of this survey included:
- Detection of galaxies in the "Zone of Avoidance", a strip of sky obscured in visible light by our own galaxy, the Milky Way.
- Detection of brown dwarfs. 2MASS discovered a total of 173, including 2MASS 0939-2448, 2MASS 0415-0935, 2M1207, and 2MASS J04414489+2301513.
- An extensive survey of low mass stars, the most
