[edit] Success at GA

Yes, this is a good article. Succinctly, it fulfills all the good article criteria. I recommend nominating it for a featured article immediately. ScienceApologist (talk) 23:37, 26 December 2007 (UTC)

Please have the person who passed the GA add the correct template, which includes a date, oldid and topic. I do not participate in GA, and I have tired of tracking down faulty GA passes to prep the article for GimmeBot closing of FACs. SandyGeorgia (Talk) 05:14, 27 December 2007 (UTC)
Jeez, I think that all this "correct template" nonsense is really getting out-of-control. Anyway, I did it. ScienceApologist (talk) 18:50, 27 December 2007 (UTC)

[edit] OK; there are now way too many pictures

Either this article needs to be increased in size by about 150 percent, or some of the pictures need to be pruned, because right now this article is almost impossible to read. Serendipodous 02:05, 1 January 2008 (UTC)

OK, I reordered the images and removed two which I felt didn't really add any new information. I think the page is much more readable now. I've also edited the captions down to stop the images crashing into each other.Serendipodous 02:14, 1 January 2008 (UTC)
I disagree with your assertion that the 2 images you deleted didn't add any new information. You deleted the only close-up of the Europan surface, and the only detailed image showing the variety of geological processes that are superimposed on the surface. Europa's fascination is mainly derived from its active geology and the amazing, alien-appearing surface manifestations of this geology, which are only visible in reasonably high-resolution images. At this point we have 3 such images; from my perspective, they're the most valuable images in the article. Let's try to keep them (or substitute better images if such are available). A lot of the other images in the article are either of limited relevance (the images of Earth's ocean floor), of limited interest (the diagrams of the interior models and magnetic field don't convey much information), or are based on speculation (the cryobot is not going to happen any time soon). So if we still have too many pictures, let's not toss the few that show the details of surface geology. WolfmanSF (talk) 05:32, 30 January 2008 (UTC)

[edit] thanks

very interesting. well done. kerfuffle (talk) 05:20, 26 February 2008 (UTC)

thank you all, editors, for this article! 98.199.206.122 (talk) 07:04, 26 February 2008 (UTC)

Thank you. Nice to know the article is helping people. Serendipodous 09:05, 26 February 2008 (UTC)

[edit] Question:

If Europa were somehow warm enough would the Oxygen be breathable by us? —Preceding unsigned comment added by 165.155.110.74 (talk) 17:10, 26 February 2008 (UTC)

Too thin -- see the Atmosphere section.Fritter (talk) 19:23, 26 February 2008 (UTC)
If Europa were closer to the Sun, it would be gradually boiled away. As its surface were reduced first to ice and then to steam, it might have a thick atmosphere for a relatively brief time, geologically speaking, and during that time, disassociation would probably create a small amount of free oxygen in the atmosphere, but it wouldn't last. Europa just doesn't have enough gravity to hold on to its air. Eventually it would be reduced to a barren airless core. Serendipodous 20:07, 26 February 2008 (UTC)

[edit] Isn't this Repetition? Opinion please

Europa is the sixth-nearest and fourth-largest moon of the planet Jupiter. Europa was discovered in 1610 by Galileo Galilei (and, some say, independently by Simon Marius), and named after a mythical Phoenician noblewoman, Europa, who was courted by Zeus and became the queen of Crete. It is the smallest of the four Galilean moons.Yyem (talk) 12:22, 28 February 2008 (UTC)

yeah, you're probably right. That sentence doesn't read well anyway. Serendipodous 12:24, 28 February 2008 (UTC)

[edit] In Odyssey Two

Hi, I'm mildly surprised there's no mention of 2010: Odyssey Two. 2010 is definitely notable IMHO. --Kjoonlee 00:15, 8 March 2008 (UTC)

2010 is mentioned more than once on Jupiter's moons in fiction, which is linked to at the bottom of the article. --Patteroast (talk) 00:47, 8 March 2008 (UTC)
Ah, thank you! :) --Kjoonlee 09:00, 8 March 2008 (UTC)


[edit] Pointless statement about mass

Isn't this rather an uninteresting fact: "its mass nonetheless significantly exceeds the combined mass of all moons in the Solar System smaller than itself"? Suggest we delete this. LarsHolmberg (talk) 20:36, 21 March 2008 (UTC)

"Uninteresting" is a fairly subjective assessment. Irrellevant to the article, inaccurate, out of date, these are reasons for deletion. But deleting a fact because it is "uninteresting" isn't really encyclopedic. There are many who would find this entire article uninteresting.Serendipodous 09:16, 22 March 2008 (UTC)


[edit] Don't you mean 'Satellite'?

Isn't the correct term for a body orbiting any planet a 'satellite', not a 'moon'? Moon is the proper name of the satellite orbiting our planet, Earth. Thoughts on this? This correction would have to be made across many wikipedia entries. —Preceding unsigned comment added by 99.249.31.69 (talk) 21:43, 28 March 2008 (UTC)

Wikipedia uses "moon" as standard, presumably because "satellite" leaves open the question as to whether it is a natural or artificial satellite. Serendipodous 23:46, 28 March 2008 (UTC)
When you refer to a 'moon' (lower-case) it means any natural satellite, while the 'Moon' (upper-case) is Earth's only moon. That's a pretty pretty standard usage as far as I've seen, and what Wikipedia uses. --Patteroast (talk) 02:16, 29 March 2008 (UTC)
