The
possibility of superfluidity in infinite nuclear matter and atomic
nuclei was suggested more than 50 years ago, shortly after the BCS
theory for metallic superconductivity was proposed. In the mean time
BCS-type pairing became fundamental for understanding many properties of
nuclei. In the past years new features of pairing correlations have
emerged in relation to the unstable nuclei produced in supernova
explosions as well as in the new generation of radioactive beam
facilities around the world. On the other hand, in the past years the
superfluidity of infinite nuclear matter became of great importance for
understanding many properties of neutron stars, such as cooling, giant
glitches, etc. Of special interest are the recent data on cooling of the
neutron star in Cassiopeia A, which seems to provide the first direct
evidence of nuclear superfluidity in nature. In this conference it will
be discussed the present status of the subjects mentioned above.
