Euclid is the next ESA mission devoted to Cosmology. The mission is expected to be launched in year 2020 and to last six years. The main scientific aim is the study of Dark Energy and Dark Matter. These will be complementarily studied to unparalleled levels via gravitational lensing and clustering (Baryonic Acoustic Oscillations, redshift distorsions) that will be measured over a total area of ~15,000 square degrees. Other cosmological probes will be high redshift clusters with measured masses and cross correlations of the lensing maps with the CMB. Since the survey area will cover most of the extragalactic sky, the wealth and quality of the data (a few billions galaxies) will be valuable to several areas in astrophysics. Aiming for a general audience, we will review the scientific problem, the main probes and related methods, and the mission characteristics.
