A wealth of astronomical data has been made available by new Earth and space based astronomical observatories. Large area telescopes have allowed detailed elemental (and sometimes isotopic) abundances to be determined in a variety of locations. Further, analysis of elemental abundances found in meteoritic inclusions have also yielded exciting and surprising results. Finally, neutrino detectors, such as SNO, are providing a detailed look at the inner workings of our Sun (and at the nature of neutrinos) and allow us to make a detailed comparison of observed neutrino flux to that predicted by standard solar models. All of this observational data provides a challenge to nuclear physics, as interpretation of this data requires nuclear reaction rates, and nuclear properties for radioactive nuclei. This talk will review the current status of techniques used to determine astrophysically important nuclear reaction rates for radioactive isotopes. Topics addressed will include the determine of astrophysical S-factors by indirect techniques, such as Coulomb breakup and nucleon transfer, and the use of nuclear charge exchange reactions to determine weak interaction strengths, which are relevant to core collapse supernovae calculations and the modelling of neutron star surfaces.
