It's cold out, Io!
If you've ever resented crunching frost underfoot on a cold morning, spare a thought for Jupiter's moon Io: when it's in eclipse, the frost on the ground is a big chunk of its atmosphere. That's the conclusion of research that looked at Io's atmosphere: when it passes behind Jupiter, Io cools down from a balmy -235°F (-148°C) …
> We lost sulphur, but we got aluminium!
Except that they then immediately proclaimed their misspelling of aluminium to be an "official acceptable alternative*" - instantly making a mockery of the entire "official spelling" sham.
Not that the banal linguistic decrees of a clique of chemists are of any value at all anyway. There's still not (and will never be) any "f" in ancient Greek (Phi was a "ph" and is always correctly translated/transliterated as such) so that particular "IUPAC" pronouncement is simply incorrect.
*probably in fact an "official acceptable alternate" as they're clearly barely literate... but they tried to mean alternative.
...and since we're being pedantic... If it "falls" it'll be "as snow", not "as frost", since snow is our analogue of frozen atmosphere crystals falling to the ground. Frost doesn't fall, it forms in situ and just sits there.
Not that the source appears to make any reference to it falling at all, so it's probably just deposited in situ... just like frost in fact... without falling anywhere...
A quick search for 'day length on io' got this page as the first result:
The author quotes a 2006 book, "Io After Galileo, A New View of Jupiter’s Volcanic Moon" by Rosaly M.C. Lopes and John R. Spencer. It seems like the loss of atmosphere was known at least 10 years ago. So what's the news here?
Io cools down from a balmy -235 °F (-148°C) to a frigid -270°F (-168°C)
According° to Wikipedia, SO2 boils at 14 °F (-10 °C) and freezes at -98 °F (-72 °C), in which case, at Io's referenced temperatures, it should be lying around on the ground all day. Is the difference due to the pressure, or is there an error in values, conversions, or am I missing something here?
I thunk we can cheque that hoot, on tea hay bie.
< aluminum and sulphur in my books, but we're all confused over here since we have the USA too close, (U saving apparatchiks) and our east coaster brethren what make us great lobster. I suspect that someone wants some dark side photography to confirm this concept in situ since we have the observer in place now.>
