- Voyager mapped only the hemisphere that faces Neptune, but revealed a very young surface scarred by rising blobs of ice (diapirs), faults, and volcanic pits and lava flows composed of water and other ices.

Aug 6, 2020 · Voyager 2’s observations exposed its icy surface, at equilibrium with a tenuous atmosphere, measuring a pressure of just 14 micro-bar (McKinnon and Kirk, 2014, In: Encyclopedia of the Solar System, pp. 861-881). Images showed a variety of morphologies consistent with recent geological activity.

five-mile-tall, geyser-like plume of dark material has been discovered erupting from the surface of Neptune's moon Triton in one of the images returned last month to the Jet Propulsion Laboratory, Pasadena, Calif., by NASA's Voyager 2 spacecraft.

Feb 27, 2023 · When Voyager 2 flew past Triton 143 years after its discovery, it revealed very few craters, indicating that Triton’s surface is relatively young: perhaps 50 million years old, or possibly even less than 10 million years old.
Voyager 2 as it coasted past the Gas Giant Neptune. Credit: NASA/JPL. We now know that Triton has had a continuous and vigorous geological activity for at least the last tens of millions of years and that a potentially habitable ocean could exist under its cold surface.
Nov 13, 2022 · Due to its geysers, which Voyager 2 identified as dark streaks, Triton is only the third known planetary body in the solar system to be volcanically active, aside from Earth and Jupiter’s...
Aug 19, 2022 · This trajectory allowed Voyager 2 to observe Neptune’s large moon Triton, the last solid object it explored. During the encounter, it returned more than 9,000 images of the planet, its atmosphere, dark rings, and moons, discovering six new moons.

High-resolution view of Triton's surface from Voyager 2 On its closest approach to Triton on August 25, 1989, Voyager snapped several high-resolution mosaics. Triton is considered to be a Kuiper belt object that was captured into Neptune orbit, an event that would have heated it and altered its surface through cryovolcanism.
