Undertoad Monday Feb 12 11:16 AMFebruary 12, 2007: Io, moon of Jupiter
It's Neatorama collaboration Monday!
Yesterday's Astronomy Pic of the Day is today's Neato collaboration.
The last time IotD mentioned Io, it sparked a lot of interest. Io is interesting partly because of the two big zits on it. One is in purple, exploding at the top of the shot; the other is pretty much in the middle, looking like a belly button on the thing.
These are active volcanoes, making Io one of the most remarkable places in the solar system. Tidal forces are causing it to have some sort of internal friction, heating it up and blowing it inside out. Like the heat when you rub your hands together, if you did it really fast, so fast that your flesh melted and came out the edge?
APoD sez the one in the middle has been noticed every time Io has been looked at, the first time being in 1979. It's been an active volcano for at least 18 years.
The hole at the top is spewing stuff out 140 kilometers (86 miles) high.
Cellar IotD has managed to not make any fart jokes during this entry.
Be sure to visit Neatorama for more neato items every day!

sorry, just invoking the term?....that counts as a fart joke.
lumberjim Monday Feb 12 11:25 AMare the colors altered in that? crazy if they're not. yellow green clouds, red land masses, purple water. has to be life there.

You're right of course, and it wasn't a very good one!
Happy Monkey Monday Feb 12 12:16 PMMost astronomy pics are color-altered, but the description just says that one has been sharpened, so maybe those are the real colors.
TorasMommy Monday Feb 12 12:17 PMThe one in the middle that "looking like a belly button on the thing" looks like it's dribbling out something red..
Otherwise that is an awesome pic..
oh and carry on with the fart jokes! Makes my day interesting...
bigw00dy Monday Feb 12 12:38 PMI love the astronomy 'pic of the day' website!!
Sarasvati48 Monday Feb 12 12:53 PMIo
That whole thing is the big pizza zit on the face of the universe...
Sheldonrs Monday Feb 12 01:07 PMIo, Io, it's where the fart jokes go.
Sundae Monday Feb 12 01:24 PMI guess bringing Uranus into it would be a step too far....?

Better than bringing IT into Uranus. lol!!!
barefoot serpent Monday Feb 12 01:34 PMThis article discusses the various colors of Io as variants of both allotropes and compounds of sulfur.
H2S it's what makes... oh, n/m!
Elspode Monday Feb 12 02:12 PMAs a satellite of Jupiter, Io is subjected to pretty much unimaginable tidal stresses. It is played almost like an accordion, in the geological sense.
LJ...life would be tough there, even for bacteria...Jupiter also has an unimaginable charged particle field which surrounds it; much of that field is inhabited by - sulphur ions! - which are spewed forth from Io and then become entrapped in the electromagnetic field of Jupiter.
Such particle bombardment makes getting life started very difficult, no matter how much sulphur it likes to eat.
Phil Monday Feb 12 02:29 PMyes, but who put it there?
Happy Monkey Monday Feb 12 02:58 PMThe obelisks.
barefoot serpent Monday Feb 12 03:26 PMor maybe the monoliths...
Happy Monkey Monday Feb 12 03:28 PMDOH!
Elspode Monday Feb 12 04:18 PMNo, no, no...that was Europa.
Happy Monkey Monday Feb 12 04:41 PMYeah, that one was deliberate, but combined with the other one, bleah.

I think that red thing is the shadow of the volcanic plume.
Wombat Monday Feb 12 06:07 PMI like how a lot of space pics look like a lot of deep-sea pics.
Cloud Monday Feb 12 06:10 PMyuck. Looks like an oozing carbuncle
xoxoxoBruce Monday Feb 12 07:51 PMFarts, zits, carbuncles...... I'm not eating todays IOtD.
Gawa Tuesday Feb 13 12:51 PMIf you look at the upper right on the sphere, you'll see a weasel-like head taking a bite out of the Northern Siberian area.

Oh no, not again! Really cool video, de-bunking the "face" on Mars (via GreatBloke's thread on Soundchain).
