The Nuclear Incompressibility parameter is one of three important components characterizing the nuclear equation of state. It has crucial bearing on diverse nuclear and astrophysical phenomena, including radii of neutron stars, strength of supernova collapse, emission of neutrinos in supernova explosions, and collective flow in medium - and high-energy nuclear collisions. In this talk I will review current status of the research on direct experimental determination of nuclear incompressibility via the compressional-mode giant resonances. In particular, recent measurements on a series of Sn isotopes have provided a value for the symmetry- energy term which directly influences the understanding of the radii of neutron stars. The Sn work has also raised very interesting questions about effects of superfluidity on nuclear incompressibility.
