Scientists anticipated a cratered, frozen moon, similar to other outer Solar System bodies. Instead, Voyager 2 found an active, dynamic world, with nitrogen plumes, smooth plains, and evidence of ongoing geological renewal. These revelations forced a major shift in how scientists defined &#8216;active worlds&#8217;. Icy moons at the edge of the Solar System could no longer be dismissed as dormant, they might conceal internal processes as complex as those of larger planets.<\/p>\n","protected":false},"excerpt":{"rendered":"Before 1989, expectations for Triton were minimal.
