The Lower Atmosphere of Pluto Revealed
Matt_dk writes "Using ESO's Very Large Telescope, astronomers have gained valuable new insights about the atmosphere of the dwarf planet Pluto. The scientists found unexpectedly large amounts of methane in the atmosphere, and also discovered that the atmosphere is hotter than the surface by about 40 degrees, although it still only reaches a frigid minus 180 degrees Celsius. These properties of Pluto's atmosphere may be due to the presence of pure methane patches or of a methane-rich layer covering the dwarf planet's surface."
Given that it has both a moon and an atmosphere, are they going to admit that it's a planet (albeit a weird one) -- or do we let the definition become so strict that soon nothing qualifies as a planet anymore?
