Dust tail of a comet

Dust tail of a comet

Fig. 14.14 . This photograph of comet West (1976 VI) shows a broad, curved, pearly-hued dust tail. Because dust particles scatter sunlight, the dust tail has a slightly yellow color. It has a delicate lacy structure, created by countless dust particles shed from the comet nucleus over many days. (Courtesy of Stephen Larson, LPL/U. Arizona.)
