Haze heats Pluto’s atmosphere yet explains its cold temperature

Modelling results find that the temperature of Pluto’s atmosphere is regulated by haze particles rather than gas molecules, suggesting that Pluto should be brighter than previously thought at mid-infrared wavelengths. Pluto's atmospheric temperature has been observed to be colder than predicted by standard theory. One possible explanation is the presence of water vapour, but it would have to be many orders of magnitude out of equilibrium to...
