Abstract
In this report I will give a brief discussion of some spectroscopic properties of comets to supplement Whipple’s excellent summary of the nature of comets. These points will be followed by presentation of the problem of cosmic ray irradiation of comets in the long time they survive in the Oort Cloud. A more detailed discussion of this phenomenon, including an experimental investigation of ice irradiation by 1 MV proton, will be given by Marla Moore. The concluding section is a hypothesis on the origin and structure of cometary nuclei.
