This image montage shows comet Hartley 2 as NASA EPOXI mission approached and flew under the comet. The images progress in time clockwise, starting at the top left.
NASA NEOWISE spotted Comet C/2013 UQ4 Catalina, appearing to be a highly active comet one day past perihelion on July 7, 2014.
NASA’s Solar TErrestrial RElations Observatory, STEREO has observed the recently discovered Comet Jacques as it passed by its nearest approach to the Sun (July 1-6, 2014). The wide field instrument on board STEREO (Ahead) showed the comet with its elongated tail being stretched and pummeled by the gusty solar wind streaming from the Sun. Also visible near the center of the image is the bright planet Venus. The Sun is just out of the field of view to the right. Comet Jacques is traveling through space at about 180,000 km per hour (110,000 mph). It may brighten enough to be seen with the naked eye.

Steve Chesley, Stardust NExT co-investigator, the Jet Propulsion Laboratory, holds up a model of Comet Tempel 1 during a news briefing, Wednesday, Jan. 19, 2011, at NASA Headquarters in Washington. On Feb. 14, 2011 NASA’s Stardust-NExT (New Exploration of Tempel 1) mission will encounter Comet Tempel 1, providing a unique opportunity to measure the dust properties which will also provide a comparison between two observations of a single comet, Tempel 1, taken before and after a single orbital pass around the sun.
