  In this review we discuss constraints on minimal supersymmetric models of
particle physics implied by the recent astrophysical observations of WMAP.
Although the prospects of detecting supersymmetry increase and 90 percent of
the available MSSM parameter space can safely be reached by the sensitivity of
future colliders, nevertheless we pay particular emphasis on discussing regions
of the appropriate phase diagrams, which -if realized - would imply that
detection of supersymmetry, at least in the context of minimal models, could be
out of colliders reach. We also discuss the importance of a precise
determination of the radiative corrections to the muon anomalous magnetic
moment, both theoretically and experimentally. Finally, we briefly commend upon
recent evidence, supported by observations, on a dark energy component of the
Universe, of as yet unknown origin, covering 73 percent of its energy content.
