  A cosmological model with total density close to critical (and flat
geometry), dominated by dark matter and dark energy of unknown nature, and
consistent with the basic predictions of the inflationary scenario is a very
good fit to a variety of cosmological probes: the anisotropy of the CMB, the
large scale distribution of matter, the luminosity distance of high-redshift
type Ia supernovae and so on. These high-quality data have established a new
standard of precision in the determination of cosmological parameters.
