  We present a new (V,B-V) Color-Magnitude Diagram (CMD) of the Carina dwarf
spheroidal (dSph) that extends from the tip of the Red Giant Branch (RGB) down
to about V=25 mag. Data were collected with the Wide Field Imager (WFI)
available at 2.2m ESO/MPI telescope and cover an area of about 0.3 square
degrees around the center of the galaxy. We confirm the occurrence of a
substantial amount of old stars with ages around 11 Gyr, together with an
intermediate-age population around 5 Gyr. Moreover, we also detected a new
well-defined blue plume of young Main-Sequence (MS) stars with an age at most
of the order of 1 Gyr. At odds with previous results available in the
literature we found thatstars along the RGB of the old and of the
intermediate-age stellar populationindicate a mean metallicity roughly equal to
Z=0.0004 and a small dispersion around this value. We find evidence for a
smooth spatial distribution of the "intermediate-age" stellar population, which
appears more centrally concentrated than the oldest one.
