This image shows comet Tempel 1 as seen through the clear filter of the medium resolution imager camera on NASA Deep Impact. It was taken on June 29, 2005.
NASA Deep Space 1 flew by comet Borrelly on September 22, 2001 and took these measurements with its plasma instruments. These data show that the flow of ions around the comet rocky, icy nucleus.
These images taken by NASA’s Stardust spacecraft highlight the diverse features that make up the surface of comet Wild 2, showing a variety of small pinnacles and mesas seen on the limb of the comet and the location of a 2-kilometer (1.2-mile) series of aligned scarps, or cliffs, that are best seen in the stereo images. http://photojournal.jpl.nasa.gov/catalog/PIA06284
61C-05-026 (14 Jan. 1986) — Astronaut George D. Nelson smiles for a fellow crew man’s 35mm camera exposure while participating in the Comet Halley active monitoring program (CHAMP). Camera equipment and a protective shroud used to eliminate all cabin light interference surround the mission specialist. This is the first of three 1986 missions which are scheduled to monitor the rare visit by the comet. The principal investigators for CHAMP are S. Alan Stern of the Laboratory for Atmospheric and Space Physics at the University of Colorado; and Dr. Stephen Mende of Lockheed Palo Alto Research Laboratory.

Comet ISON is heading for a Thanksgiving Day brush with the sun, but first it’s going to pay a visit to Mars. In this week’s ScienceCast, researchers discuss what might happen when Comet ISON meets the Red Planet.
This illustration shows a star behind a shattered comet. Observations of the star KIC 8462852 by NASA’s Kepler and Spitzer space telescopes suggest that its unusual light signals are likely from dusty comet fragments, which blocked the light of the star as they passed in front of it in 2011 and 2013. The comets are thought to be traveling around the star in a very long, eccentric orbit. http://photojournal.jpl.nasa.gov/catalog/PIA20053
This image of comet 67P/Churyumov-Gerasimenko was taken by the Onboard Scientific Imaging System OSIRIS on the European Space Agency Rosetta spacecraft on June 4, 2014.
