NASA's Voyager 2 spacecraft flew by Triton, a moon of Neptune, in the summer of 1989. Dr. Paul Schenk, a scientist at the Lunar and Planetary Institute in Houston, used Voyager data to construct the best-ever global color map of Triton.
This map composed of images NASA's Galileo and Voyager missions shows the hemisphere of Europa that might be affected by plume deposits. The view is centered at -65 degrees latitude, 183 degrees longitude.
This is a frame from an animation of a rotating globe of Jupiter's moon Ganymede, with a geologic map superimposed over a global color mosaic, incorporating the best available imagery from NASA's Voyager 1 and 2 spacecraft, and Galileo spacecraft.
Ganymede Global Geologic Map and Global Image Mosaic
To present the best information in a single view of Jupiter's moon Ganymede, a global image mosaic was assembled, incorporating the best available imagery from NASA's Voyager 1 and 2 spacecraft and NASA's Galileo spacecraft.
This graphic shows the location of water vapor detected over Europa's south pole in observations taken by NASA's Hubble Space Telescope in December 2012. This is the first strong evidence of water plumes erupting off Europa's surface.
The image taken by the Oschin Schmidt Telescope, shows the star AC +79 3888, also known as Gliese 445. NASA's Voyager 1 spacecraft, which is on a trajectory out of our solar system, is headed toward an encounter with AC +79 3888 (circled in red).
This artist's concept shows the general locations of NASA's two Voyager spacecraft. Voyager 1 (top) has sailed beyond our solar bubble into interstellar space. Voyager 2 (bottom) is still exploring the outer layer of the solar bubble.
Radio telescopes cannot see Voyager 1 in visible light, but rather "see" the spacecraft signal in radio light. This image of Voyager 1's signal on Feb. 21, 2013. At the time, Voyager 1 was 11.5 billion miles (18.5 billion kilometers) away.
Titan's polar collar, previously seen by Voyager 2 and the Hubble Space Telescope, has now been observed by the Cassini spacecraft, seen here in ultraviolet light. The collar is believed to be seasonal in nature.
The area within Saturn's north polar hexagon is shown by NASA's Cassini spacecraft to contain myriad storms of various sizes, not the least of which is the remarkable and imposing vortex situated over the planet's north pole.
