Abstract
We give an overview of Euclid, a space mission selected for study within ESA’s Cosmic Vision framework. Euclid is
a survey mission which aims to deeply cover the whole extragalactic sky (2 sr). Exquisite optical imaging in one wide optical
band plus deep photometry in three NIR bands will allow to map gravitational lensing across the sky, while NIR spectroscopy
will allow a full sky sample of accurate galaxy redshifts up to z 2. These measures will allow to probe with unprecedented
accuracy presence and characteristics of Dark Energy, Dark Matter and possible presence of non standard gravity. The giant
database will also have an enormous legacy value and allow the exploitation of countless science topics
