Implication

Observational review reveals unexpected ultraviolet extinction features in interstellar dust, indicating compositions differ fundamentally from dirty ice models.

Key Points

To review how ultraviolet observations have transformed scientific understanding of interstellar dust particle composition and extinction behavior.
Synthesis of astronomical observations assessing dust properties via ultraviolet extinction curves.
Evaluation of rocket-borne ultraviolet spectrophotometry measuring starlight absorption down to 0.22 μm and shorter wavelengths.
Identification of a pronounced ultraviolet interstellar extinction peak at 0.22 μm, disproving the prior assumption of a maximum at 0.3 μm.
Detection of a steep, continuous increase in extinction toward the shortest measurable wavelengths, overturning the hypothesis that interstellar particles consist primarily of dirty ices.
