[edit]Resolved comments.

Here are some comments on the article's prose. Please to respond to the concerns individually to clarify which are done and which need further discussion.
- "Improved telescope technology in the late 19th and 20th centuries allowed astronomers to resolve (that is, see)" I strongly disagree with the inclusion of this parenthetical comment, as it is an awkward intrusion to the sentence. The linked article (optical resolution) adequately explains the rather intuitive meaning of the term within the first sentence.
- I am a tad confused by the fact that the last sentence of the first paragraph in the lead deals with the 60s, whereas the first sentence of the next paragraph deals with the 50s. The former seems to be a somewhat trivial (and vague) bit for the lead, so why not remove it to preserve the timeline?
- "is on their short list of large-scale missions" The juxtaposition of "short" and "large" here is somewhat confusing. Suggest rewriting to "one of their large-scale missions" or "one of several large-scale missions".
- "During his observation of Jupiter on the evening of January 7, Galileo spotted two stars to the east of Jupiter and another one to the west" ...but they're not actually stars. Suggest inserting "what he believed to be" before "two stars".
- "Jupiter and these three stars appeared to be in a line parallel to the ecliptic." "In a line" implies that you're waiting to get your license renewed at the Department of Motor Vehicles. The more correct mathematical phrase would be "on a line". Agreed?
- "Galileo's telescope, while having a high magnification for a telescope from his time, was too low-powered to separate the two moons into distinct points of light." My limited understanding of optics tells me that optical resolution and magnification are two distinct properties of telescopes. If the telescope was unable to resolve the two moons into distinct points, it was because of the resolving power, not the magnifying power.
- "Galileo observed Jupiter the next evening, January 8, 1610, this time seeing three stars to the west of Jupiter, suggesting that Jupiter had moved to the west of the three stars." This sentence does not make sense. If the three stars were to the west of Jupiter, wouldn't it be more correct to say that Jupiter had moved to the east of the stars?
- "This was the first time that Io and Europa were observed and recorded as distinct points of light so this date, January 8, 1610 is used as the discovery date for the two moons by the International Astronomical Union." Awkwardly long sentence and informal use of "so". Suggest breaking it up with a comma and rewording.
- "These were the first moons of a planet other than the Earth to be discovered." Citation needed, big time.
More to come. --Cryptic C62 · Talk 22:43, 24 March 2010 (UTC)

Missed Opportunity
[edit]Didn't Pioneer 10 have radiation-related problems during it's encounter with Io that prevented better images? This is worth mentioning in my opinion. --2605:E000:8643:9B00:C991:BFC5:4B0F:CF6A (talk) 05:52, 6 March 2015 (UTC)
- This is mentioned in the article: "Close-up images using Pioneer's Imaging Photopolarimeter were planned as well, but were lost because of the high-radiation environment.[34]" --Volcanopele (talk) 20:25, 6 March 2015 (UTC)

Handwritten note removal
[edit]In the Discovery section, there is a figure showing a handwritten note from Galileo with his initial drawings of the positions of Jupiter's four major satellites. In 2022, this was shown to be a 20th century forgery per The NY Times link below and I have removed the figure.
