Halley's Comet as photographed May 8, 1910, by Dr. G.W. Ritchey using the 60-inch (1.5-meter) telescope at Mount Wilson Observatory, Calif., during the comet's last appearance. The head of the comet and the beginning of its long tail are shown. Short, straight streaks are background stars. The comet, due to return to the Sun's vicinity in 1986, will be the object of a worldwide observation effort by professional and amateur astronomers. Jet Propulsion Laboratory is the western hemisphere lead center for the International Halley Watch.
