2MASS the 2 Micron All Sky survey is an all sky survey in the 2 micron range that used both northern and southern hemisphere telescopes to cover the whole sky from 1997 through 2001 with a final post processing release in 2003.
According to wikipedia, the goals of 2MASS were to look into the areas of the Milky way hidden in visible light, to look for brown dwarfs and low mass stars and to create a catalog of all of the galaxies and stars 2MASS could detect.

- wavelengths J (1.25 um), H (1.65 um), and Ks (2.17 um) in the Near Infrared (NIR)
- over 500 million sources in the point source catalog
- 1.6 million sources in the extended source catalog (I don't know what this means yet:)
- catalogs publicly available.
Add where it fits with other scopes and what it is typically used for???
