Resumen:
When a star explodes as a supernova (SN), about 1051 ergs of energy are released in the interstellar medium (ISM). Most SN outbursts occur near or inside the molecular clouds were their pogenitor stars were born. An increasing number of SN remnants (SNRs) show signatures of being inter- acting with neighbouring clouds. Understanding such interactions is cru- cial both to determine the physical and dynamical conditions and structure of the ISM and to learn about the physical processes that take place in an SNR shock front. Even if molecular clouds are absent, pre-existing mag- netic fields can play a key role on the morphology of an SNR. In this paper I review some recent results on the interplay between Galactic SNRs and their surroundings.
