Comets

Halley1	The nucleus(!) of Halley's comet imaged by the Giotto spacecraft in March, 1986. Here's a movie of the approach to the nucleus!
West1	Comet West on March 9, 1976.
Borrelly	The nucleus of comet Borrelly obtained on September 22, 2001 by the Deep Space 1 spacecraft just 160 seconds before closest approach. The comet nucleus is about 5 miles long and was viewed from a distance of 3417 kilometers.
Comet Dust	Close view of an interplanetary dust particle.
Comet Tail Movie	This movie shows changes in the tail of comet Ikeya-Zhang during 30 minutes on March 11, 2002. It shows ten consecutive 3-minute exposures.
Wild2	On January 2, 2004 the Stardust spacecraft made a close flyby past the comet Wild2 (pronounced Vilt2) which was 242 million miles from Earth at the time. The spacecraft got within 149 miles of the comet nucleus, passing by at a relative speed of 13,645 mph! Here is a fantastic picture of the comet's 3.4-mile wide nucleus as well as a movie of the flyby. The spacecraft also captured samples of comet dust which are scheduled for return to Earth in January, 2006.
Ikeya-Zhang	Fantastic picture of comet Ikeya-Zhang in the same field of view as the Andromeda Galaxy on April 5, 2002. The galaxy is 2 million light years away, but the comet is only 4 light minutes away!
Schwassmann-Wachmann 3	This movie, made at our own Winfree Observatory, shows two hours of comet 73P/Schwassmann-Wachmann 3 's orbital motion against the background stars in the constellation Corona Borealis on April 27, 2006.
