Abstract

THE interstellar extinction curve recently extended into the far ultra-violet1,2 has revealed a structure which cannot be fitted by ice grains of the type proposed by van de Hulst3. The theoretical extinction curve predicted for graphite grains has, however, been shown to fit the observations much better4,5, indicating that graphite rather than ice may be the major contributor to interstellar extinction.
