Neptune's New Icy Companions

An anonymous reader writes "The Harvard-Smithsonian Center for Astrophysics has announced new moons found around Neptune. The findings represent the first discovery of moons from ground-based telescopes in more than a half-century (1949), and required an international team to track and confirm. Notable about the ice-planet Neptune is also its largest moon-Triton-which is the coldest measured object in our solar system, and as a consequence even its volcanoes spew not lava, but ice."
