The Large Area Telescope (LAT), one of the two instruments on the Fermi Gamma-Ray Space Telescope (formerly GLAST, launched June 11, 2008) is a pair conversion detector designed to study the gamma-ray sky in the energy range from 20 MeV up to 300 GeV. The greatly improved sensitivity of the LAT compared with its predecessor experiment, EGRET on the Compton Gamma-Ray Observatory, together with the uniform and deep sky coverage, provides a unique capability for studying the gamma-ray Universe. The Fermi Telescope probes relativistic outflows and acceleration mechanisms in objects such as supernova remnants, pulsars, active galactic nuclei and gamma ray bursts and may also shed light in the origin of dark matter. The LAT has detected many gamma-ray sources and the diffuse emissions of the Milky Way with unprecedented sensitivity and resolution. After a brief overview of the instrument and status, I will concentrate on the results obtained on these topics for
the first year of the Fermi/LAT mission.
