- This is the first time geyser-like phenomena have been seen on any solar system object (other than Earth) since Voyager discovered eight active geysers shooting sulfur above the surface of Jupiter's moon, Io.

Sep 10, 2019 · As well as revealing geologically young surfaces, Voyager 2 saw active geysers spewing material, tell-tale signs that Triton is active despite having the coldest surface temperature (-391°...
Aug 25, 2014 · Voyager scientists were also amazed to see that Triton, a moon of Neptune, has active geysers. "The Triton flyby was my favorite moment partly because it was a bookend. The journey really started with the discovery of volcanoes on Io with Voyager 1, 10 years earlier -- the first bookend.

Voyager 1 flew within 277,400 kilometres of Jupiter on March 5, 1979, while Voyager 2 came within 650,180 kilometres on July 9, 1979. The Voyagers took images that showed plumes from volcanoes on the surface of Io, one of Jupiter's moons. 1. Galileo takes closer look at Io It was the first time an active volcano was observed in our solar system bey...
The Voyagers also took images of Europa, another one of Jupiter's moons. Those images showed cracks on the surface, which were filled in with a dark, icy material. This was the first hint for scientists of water underneath the surface of Europa. 1. Is Europa habitable? NASA mission will use these 9 instruments to find out The Galileo spacecraft mis...
On Aug. 25, 1989, Voyager 2 took the first images of Triton, Neptune's largest moon. The photos showed geyser-like eruptions shooting nitrogen gas and dust particles several kilometres into Triton's atmosphere. Due to Triton's relatively high density and retrograde orbit — orbiting in the opposite direction to Neptune's rotation — scientists determ...
On Nov. 12, 1980, Voyager 1 flew by Saturn, recording data on the planet and its many moons. It foundthat one of the moons, Titan, had a thick atmosphere mostly composed of nitrogen, like Earth's atmosphere, although the surface pressure was about 1.6 times higher. According to NASA, "The chemistry in Titan's atmosphere may strongly resemble that w...
NASA says that in August 2012, Voyager 1 became the first and, as of today, only spacecraft to enter interstellar space. Interstellar space is defined as the region between stars — and beyond the reach of the sun's constant flow of material and magnetic field, known as the heliosphere. 1. Voyager 1 probe has hit interstellar space, NASA agrees The ...
At least four active geyser-like eruptions were discovered in Voyager 2 images of Triton, Neptune's large satellite. The two best documented eruptions occur as columns of dark material rising to an altitude of about 8 kilometers where dark clouds of material are left suspended to drift downwind over 100 kilometers.

Nov 4, 1989 · The new discovery confirms that geysers are indeed active on Triton. This makes it the fourth body in the Solar System that planetary geologists know to be volcanically active.

On July 8, 2019, Voyager 2 successfully fired up its trajectory correction maneuver thrusters and will be using them to control the pointing of the spacecraft for the foreseeable future. Voyager 2 last used those thrusters during its encounter with Neptune in 1989.
