Unexpected cooling effect in Saturn's upper atmosphere

UK researchers from University College London, along with colleagues from Boston University, have found that the hotter than expected temperature of Saturn's upper atmosphere – and that of the other giant planets – is not due to the same mechanism that heats the atmosphere around the Earth's Northern Lights. Reporting in Nature (25th January) the researchers findings thus rule out a long held theory.
