Image in visible light of the surface of Triton,the largest of Neptune's moons,photographed by the Voyager 2 spacecraft on 25 August 1989 at a distance of 40,000 km. Several dark plumes are seen on the bright surface,each of which originates at a very dark spot. It is thought that these are the result of eruptive venting of dark material from below the surface,carrying it into the atmosphere. The winds then transported the erupted particles up to 100 km away from each vent. These features are seen in the southern polar region of Triton,and may be seasonal in nature | |
