Triton's Volcanic Plumes. These three sequential images of an erupting volcano on Neptune's large moon Triton were taken by NASA's Voyager 2 as the spacecraft approach the moon on Aug. 26, 1989.
Apr 29, 2024 · Kirk and Lopes note that there is evidence of past cryovolcanism on Triton, the largest of Neptune’s 13 moons. NASA’s Voyager 2 spacecraft helped scientists observe that Triton’s surface is composed of smooth plains , mounds, and rock pits.
Neptune's moon Triton was the first object where active plumes were observed by Voyager 2 in 1989, interpreted as possibly cryovolcanic. Galileo observations showed evidence of cryovolcanism on Europa and Ganymede and later observations by HST have detected possible water vapor plumes from Europa.
Aug 22, 2019 · Thirty years ago, on Aug. 25, 1989, NASA’s Voyager 2 spacecraft made a close flyby of Neptune, giving humanity its first close-up of our solar system’s eighth planet.
Sep 25, 2023 · by Erik Klemetti 25 September 2023. Ocean worlds throughout our solar system may be home to a phenomenon known as cryovolcanism, in which volcanoes erupt, ejecting volatiles such as ammonia. In...

Leviathan Patera (center) and Ruach Planitia (upper left), two large cryovolcanic features on Neptune's moon Triton. A cryovolcano (sometimes informally referred to as an ice volcano) is a type of volcano that erupts gases and volatile material such as liquid water, ammonia, and hydrocarbons.
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.
