Abstract The Two Micron All Sky Survey has imaged 100% of the celestial sphere in the near-infrared J (1.2?m), H (1.6?m) and Ks (2.2?m) photometric bands. Pipeline processing of these data has produced catalogs containing 500 million stars and 1.5 million extended sources which will be released later this year. The catalogs are characterized by great photometric uniformity (1%) and precision (2-3%) around the sky as well as good astrometric accuracy (100 mas). This talk will focus on some of the initial scientific results enabled by this database ranging from brown dwarfs in the solar neighborhood to large scale structure in the early universe.
