An oxygen-carbon dioxide atmosphere has been observed at Rhea.
National Geographic link And a rather shocking interpretation of this, Saturn's moon Rhea may have a breathable atmosphere -------------------- -- Hungry4info (Sirius_Alpha)

At least the comments are (mostly) quite properly skeptical; nobody's buying it. This site's audience seems far more informed than the author of that piece of tripe. EDIT: Just sent a blistering e-mail to the editor-in-chief of that site; let's see if it does any good. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Grr. (I'm cool, Craig, I'm cool!) Article's still up as of 26 Nov/1743 GMT, no retractions, no corrections.
Must be a US site, nobody's watching the store during the (informal) holiday here. No reply to my e-mail from last night, either. I will maintain robotic vigilance (that's the best kind, of course) over this issue -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Dropping the S/N for a sec for an artistic interpretation of the latest news.
I'm curious what the presence of the atmosphere means for those strange readings that was originally interpreted as a ring. -------------------- -- Hungry4info (Sirius_Alpha)

This exosphere is not that dense to either absorb high-energy electrons or to drive a strong interaction with the flowing plasma, like we see at Io, Europa, Enceladus etc. |
