Nereid

Nereid, the last satellite of Neptune to be discovered before NASA Voyager's recent discoveries, was first seen by Gerard Kuiper in 1949. Until this Voyager 2 image was obtained, all that was known about Nereid was its orbital parameters and intrinsic brightness. This Voyager view of Nereid was obtained on Aug. 24, 1989 at a distance of 4.7 million kilometers (2....

Concentric Rings Surrounding Valhalla

The concentric rings surrounding Valhalla are perhaps the most distinctive geological feature on Callisto. This NASA Voyager 1 close-up shows a segment of the ridged terrain.

Dark Side of Comet 67P/Churyumov-Gerasimenko Saturated

This image of comet 67P/Churyumov-Gerasimenko was obtained on October 30, 2014 by the OSIRIS scientific imaging system on the Rosetta spacecraft. The saturation of the image allows the viewer to see some surface structures on dark side of the comet.

Color Image of Pluto

Pluto nearly fills the frame in this image from the Long Range Reconnaissance Imager (LORRI) aboard New Horizons, taken on July 13, 2015, when the spacecraft was 476,000 miles (768,000 kilometers) from the surface. This is the last and most detailed image sent to Earth b...

Ariel at Voyager Closest Approach

This picture is part of NASA Voyager 2 imaging sequence of Ariel, a moon of Uranus taken on January 24, 1986. The complexity of Ariel surface indicates that a variety of geologic processes have occurred. http://photojournal.jpl.nasa.gov/catalog/PIA00037

Triton High Resolution View of Northern Hemisphere

This is one of the most detailed views of the surface of Triton taken by NASA Voyager 2 on its flyby of the large satellite of Neptune early in the morning of Aug. 25, 1989. The picture was stored on the tape recorder and relayed to Earth later. http://photojournal.jpl.nasa.gov/catalog/PIA00061
