Triton, the largest moon of Neptune, exhibits plumes of nitrogen spewing from frozen "geysers" or "cryo-volcanoes" near its south pole. While scientists struggle to comprehend them, analogous plumes and jets elsewhere in the solar system suggest that the answer may be obvious.
On August 20, 1977, NASA launched the Voyager 2 mission on a multi-year journey to the outer solar system. Twelve years after launch, on August 25, 1989, Voyager 2 was the first spacecraft to return close-up images of remote Neptune, now officially recognized as the most distant planet from the Sun (due to the downgrading of Pluto to a Kuiper Belt Object).
One of the greatest surprises of the Voyager mission occurred on the flyby of Neptune’s largest moon, Triton. To the astonishment of planetary scientists, the cameras revealed active geyser-like eruptions spewing nitrogen gas and dark dust particles straight up, eight kilometers into space. The stunned NASA investigators called these eruptions cryogenic “ice volcanoes,” and for almost two decades they have struggled to understand them.
Some theorists have attempted to leverage heat from the Sun into a plausible source of the required energy. Thus, JPL scientists suggested that, “Trapping of solar radiation in a translucent, low-conductivity surface layer (in a solid-state greenhouse)…could provide the required energy.” But others at the University of Hawaii speculated that, “heat released when frozen molecular nitrogen shifts from one crystalline state to another may fuel the geysers.”
Are these exotic proposals really plausible candidates? When Electric Universe proponents hear theoretical guesses of this sort, they see a casual disregard for the patterns of space age discovery. How many unexpected geysers will we have to see in the solar system before planetary scientists begin to ask the obvious questions?
