The COROT (COnvection, ROtation and planetary Transits) mission, very successfully launched in December 2006, is intended to provide high-precision (noise level in the frequency spectrum 0.7 ppm over a 5 d time baseline) photometric monitoring of stellar targets to achieve three main objectives: 1) stellar seismology of dwarf stars to give direct information on the structure and dynamics of their interiors (Seismology programme). Among those, a few bright stars (V<8.0) will be studied continuously for 150 days (primary targets), along with up to 9 fainter stars (V<9.5, secondary targets), located in the same field of the primary targets; 2) the detection of Earth-like planets from eclipses of their parent stars (Exoplanet programme); 3) the accurate high precision, continuous, photometric monitoring of many thousands of fainter stars that lie aside in the Exoplanetary fields. The main results obtained in the first year of observations are reviewed.
