Atmosphere of Triton asymmetry was actually observed during star occultations by Triton in 1990s. Before Voyager 2 arrived, a nitrogen and methane atmosphere with a density as much as 30% that of Earth had been suggested. This proved to be a great overestimate, similar to the predictions of the atmospheric density of Mars, but like on Mars, a denser early atmosphere is postulated. Voyager 2 flew past Triton five hours after closest approach to Neptune in mid-late August 1989. During the flyby, Voyager 2 took measurements of the atmosphere, finding methane and nitrogen in the atmosphere. In the 1990s, observations from Earth were

Gas-s-s-s Gas-s-s-s (also known as Gas! or It Became Necessary to Destroy the World in Order to Save It) is a 1970 motion picture produced and released by American International Pictures. It was producer Roger Corman's final film for AIP, after a long association. He was unhappy because AIP made several cuts to the film without his approval, including the removal of the final shot in which God comments on the action — a shot Corman regarded as one
