Cosmology is currently entering a new phase of comprehensiveness, precision and confidence. Recent developments in theoretical and observational cosmology (including accelerating expansion, cosmic microwave background anisotropy and nonzero-mass neutrino oscillations) and nucleochonometry are herein reviewed, presenting the latest values of quasar redshift, cosmological parameters in the standard model (with concentration upon the Hubble constant and the age of the Universe) and dating information from nuclear astrophysics. The methods and findings of nucleochronology, in the main based upon stellar r-process neutron capture rate data relevant to, e.g. , 137Re/137Os chronometry, Th/Eu abundance ratios and Th or U chronometry techniques are discussed in detail. Recent findings concerning the accelerated expansion of the Universe are presented, with consideration given to cosmological implications of, e.g. , dark energy, exotic dark matter, cosmic strings and supergravity. In conclusion, some remaining current problems and uncertainties are briefly noted.
