Ver en NASA ↗NASA NEOWISE mission captured images of Comet C/2013 A1 Siding Spring. The infrared pictures reveal a comet that is active and very dusty.
Ver en NASA ↗A 100 foot-wide, 28-million-pound boulder, was found to have moved 460 feet on comet 67P/Churyumov-Gerasimenko in the lead up to perihelion in August 2015, when the comet activity was at its highest.
Ver en NASA ↗NASA NEOWISE spacecraft observed the Oort cloud comet C/2006 W3 Christensen on April 20th, 2010, as it traveled through the constellation Sagittarius.
Ver en NASA ↗The Compact Reconnaissance Imaging Spectrometer for Mars CRISM aboard NASA Mars Reconnaissance Orbiter obtained this spectrum for comet C/2013 A1 Siding Spring during the comet close approach to Mars.
Ver en NASA ↗These three pairs of images from NASA EPOXI mission demonstrate that a dust jet and gaseous carbon dioxide are being released from comet Hartley 2 at the same time, and from the same location on the comet.
Ver en NASA ↗This artist depiction shows the close encounter between comet Siding Sprng and Mars in 2014. The comet powerful magnetic field temporarily merged with, and overwhelmed, the planet weak magnetic field.
Ver en NASA ↗This composite image was taken by NASA Stardust navigation camera 42 hours before its encounter with comet Tempel 1. The spacecraft is due to encounter the comet in the evening hours of Feb. 14, 2011.
Ver en NASA ↗These images were taken of comet C/2013 A1 Siding Spring by NASA Mars Reconnaissance Orbiter on Oct. 19, 2014, during the comet close flyby of Mars and the spacecraft.
Ver en NASA ↗This image was taken during the close approach phase of NASA Stardust Jan 2, 2004 flyby of comet Wild 2. It is a distant side view of the roughly spherical comet nucleus.
Ver en NASA ↗This image from an animiation of comet C/2013 A1 Siding Spring were taken by the Mast Camera Mastcam on NASA Curiosity Mars rover as the comet passed near the red planet on Oct. 19, 2014.
Ver en NASA ↗This image depicts the primary landing site on comet 67P/Churyumov-Gerasimenko chosen for the European Space Agency Rosetta mission.
Ver en NASA ↗This image from NASA Hubble Space Telescope of the sunward plunging comet ISON suggests that the comet is intact despite some predictions that the fragile icy nucleus might disintegrate as the sun warms it.
Ver en NASA ↗This frame from a movie shows the progression of NASA NEOWISE survey in the mission first year following its restart in December 2013. Each dot represents an asteroid or comet that the mission observed.
Ver en NASA ↗This montage is an artist's conception of progressive views of the Comet Kohoutek based on sketches and a description by Skylab-4 astronaut Edward Gibson. An early discovery of a large comet in an orbit that would reach close to the Sun at the end of 1973 pro…
