IZ Reloaded writes "Any would be travellers to Pluto should bring extra winter gear. The new temperature on Pluto according to scientists is 43 degrees Kelvin. That's 10 degrees Kelvin colder than expected. From CNN: "Astronomers think Pluto's colder than expected temperature reading involves interactions between nitrogen ice on the planet's surface and the nitrogen gas that makes up its atmosphere...Pluto is a dynamic example of what we might call an anti-greenhouse effect...""
