Halley Close-Up

This dramatic image shows the nucleus of Halley's Comet and the surrounding coma as viewed by the Halley Multicolor Camera on the Giotto spacecraft. The fan-shaped set of streamers extending toward the sun from the coma is composed of dust jets being blown off the comet's nucleus by the sublimation of its ices. The Giotto spacecraft was approximately 25,600 km (15,800 mi) from the comet when this image was taken in March, 1986. Giotto was sent by the European Space Agency to observe the comet.
