Scientists found that Pluto's atmosphere dramatic expansion in 14 years.

An international research team found that after a year of observations, Pluto's atmosphere dramatic expansion in 14 years, increasing pressure. .Their paper published in the new issue of the British "Nature" magazine. .In the solar system, Pluto is a planet farther from the sun, scientists have speculated it may be diminishing the pressure the atmosphere. .However, the French aerospace laboratory scientists, including an international research team, including after one year of observation and found the opposite to this the fact that Pluto's atmosphere is dominated by the accumulation of nitrogen inflation. .According to their projections, the pressure in the 14 years it may be tripled. .Because of the distance and so very much sun and the earth, human beings have not been able to patronize Pluto probe, but also more difficult to see from the Earth of its features. .Scientists came up with a method called radio occultation observation approach. .The method is based on another planet after Pluto behind the "light source", due to occlusion of the planet Pluto, so long as the analysis of the stars light the extent of losses to the atmosphere of Pluto to a preliminary analysis of the situation. .Scientists only in 1988 and 2002, respectively, have to wait until the star passed behind Pluto from the opportunity. .Observed in these two years by the Pluto data analysis, the scientists found that its atmosphere has been 14 years, severe swelling. .(Yang Jun </ p>.
