SAVE NEPTUNE NOW!!

First Mars, now Neptune... we need to shut down the Mars Rover and stop the drilling on Neptune!! :P:D:)

Mid-Infrared Ethane Emission on Neptune and Uranus

Abstract

We report 8ndash13 mum spectral observations of Neptune and Uranus from the NASA Infrared Telescope Facility spanning more than a decade. The spectroscopic data indicate a steady increase in Neptune's mean atmospheric 12 mum ethane emission from 1985 to 2003, followed by a slight decrease in 2004. The simplest explanation for the intensity variation is an increase in stratospheric effective temperature from 155±3 K in 1985 to 176±3 K in 2003 (an average rate of 1.2 K yr-1) and a subsequent decrease to 165±3 K in 2004. We also detected variation of the overall spectral structure of the ethane band, specifically an apparent absorption structure in the central portion of the band; this structure arises from coarse spectral sampling coupled with a nonuniform response function within the detector elements. We also report a probable direct detection of ethane emission on Uranus. The deduced peak mole fraction is approximately 1 order of magnitude higher than previous upper limits for Uranus. The model fit suggests an effective temperature of 114±3 K for the globally averaged stratosphere of Uranus, which is consistent with recent measurements indicative of seasonal variation.

This is a good news / bad news thing.

First the good news; The methane emissions from Uranus aren't as much as some people thought.

And the bad news; Uranus isn't as hot as people once thought it was.
