Comet Halley is shown here in a composite of images taken by the Giotto probe on 14 March 1986 from 1,500 km away. The nucleus of Halley's Comet, 16 km long, is visible. The image shows gaseous jets from evaporating ices spewing from the surface of the nucleus. (Credit: ESA/Giotto)
Comet Borrelly is seen here in an image obtained by the Deep Space 1 probe in 2001 from 3,417 km away. This shows the 8-km long nucleus of the comet. (Credit: NASA, JPL)
Comet Wild 2 is seen in this image from the Stardust probe taken on 2 January 2004 from 500 km away. (Credit: STARDUST team, NASA, JPL)
The nucleus of Comet Temple 1 is shown here in an image taken 4 July 2005 from 3,000 km away by the Deep Impact impactor probe, shortly before it struck the comet's surface. (Credit: NASA, JPL)
Comet Hartley 2 is seen here in an image from 700 km away taken 4 November 2011 by the EPOXI spacecraft. The nucleus is 2 km long. (Credit: NASA/JPL-Caltech/UMD)
Comet Churyumov-Gerasimenko is seen here in an image from 100 km away taken 11 August 2014 by the Rosetta spacecraft. The nucleus has two distinct lobes and is 4 km long. (Credit: ESA/Rosetta/NAVCAM)
