Munich, March 3 : Astronomers have used the European Southern Observatory's (ESO's) Very Large Telescope (VLT) to gain valuable new insights about the lower 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.
