(PhysOrg.com) -- Newly released images commemorate the 20-year anniversary of the Voyager flyby of Neptune's moon Triton on Aug. 24, 2009.

Triton was the last solid object visited by NASA's Voyager 2 as it headed toward the edges of our .

This simulated voyage over the surface of Neptune's large moon Triton was produced using topographic maps derived from images acquired by NASA's Voyager spacecraft during its August 1989 flyby, 20 years ago this week.

Triton, Neptune's largest moon, is one of the "coolest" objects in the solar system, literally, with a surface temperature of minus 235 degrees Celsius (minus 391 degrees Fahrenheit). Voyager 2 discovered that Triton has active geysers.

The images and a movie show the moon's sparsely cratered surface with smooth volcanic plains, mounds and round pits formed by icy flows. The Voyagers are the farthest human-made objects in the solar system. Voyager 1 is 16.6 billion kilometers (10.3 billion miles) or about 111 Astronomical Units from the Sun. Voyager 2 is 13.5 billion kilometers (8.4 billion miles) or about 90 Astronomical Units from the Sun. Both are expected to reach interstellar space in five to eight years (2014 - 2017).

I was kinda hoping that they would have newly processed images of the numerous 'ice volcanoes' discovered by Voyager 2, especially with Triton being only the third solar system body to exhibit active volcanism (after, of course,the Earth and Jupiter's moon Io). But, a great effort by all involved. Thanks for the look back.
