I appreciate you linking an actual paper, but I fear there may be a misunderstanding regarding the article quote: > > Scientists, you got some ‘splaining to do." > What is this, third grade. I suppose it may sound that way, but actually that is a dated quote from the 1960's "I Love Lucy" show. That's what her husband said every time he discovered her hijinx. As such, anyone might like or dislike the quote as a matter of taste, but it is intended to simply be a bit of lighthearted phrasing. As for Pluto, I find this phenomenon interesting but not deeply startling. Lots of things could produce outgassing, particularly considering the very long Plutonian "summers" and "winters".
