The Planetary Report • April/May 1981

Comet West

On the Cover: On its return in 1986, Comet Halley will appear similar to Comet West, seen in this photograph taken in 1976. The thirty-million-mile-long dust tail of Comet West dominates this image, while its blue gas tail glows faintly. Due to its position as it moves through the inner solar system, the apparition of Comet Halley will not be as spectacular as it has been in the past, and will best be seen from the Earth's southern hemisphere.
