  • The lede is a bit on the short side. Given that the article isn't terribly long, the lede doesn't have to be two paragraphs, but it should be longer than four lines.
  • "Andromeda is a constellation in the northern sky." - there could probably be a better opening sentence. It doesn't really say anything. Is it truly northern from wherever you look at it on Earth? Is it only visible from the northern hemisphere? Is there anything you could say to draw the reader in a bit more?
  • Given that the constellation's name is identical to its namesake, perhaps the second sentence could be something simpler like:
  • "Andromeda is prominent in the northern sky during the fall" - if you keep the current opening sentence, then this clause is redundant (sans the fall part). Given there is ambiguity about "fall" referring to verb or an action or a season, perhaps you should use Autumn?
  • I didn't learn until the fifth sentence that Andromeda is not in our galaxy. I think that should be mentioned sooner, as that's more important than what it's named after.
    • I'm not sure what you mean by this, could you explain?
      • Well, I think where the constellation is is more important than its namesake. Unless, you disagree. --♫ Hurricanehink (talk) 22:15, 1 May 2012 (UTC)[reply]
        • Hm, well, I kind of assumed that it was, but if you as a reader disagree, I'll change that. I figure clarity for non-astronomy people is paramount, especially in the lead. Is there a general wording that would help? I'm not quite sure how to change it. Keilana|Parlez ici 01:14, 2 May 2012 (UTC)[reply]
          • Oh, I completely agree it's worth having in the lede. I wasn't a fan of how it was the first important sentence of the lede, but it's much better given the new opening sentence. ♫ Hurricanehink (talk) 14:03, 2 May 2012 (UTC)[reply]
  • What exactly is a constellation as opposed to a galaxy?
    • A constellation is a collection of stars at varying distances that forms a shape as seen from Earth, which has been defined by the International Astronomical Union as a specific region of the sky. A galaxy is a gravitationally-bound collection of stars, gas, and other random objects that is all at the same general distance from the Earth. Does that help?
  • The end of the first sentence in "History and mythology" has a ")". Not sure what the ) was meant for.
  • "In the myth, Cassiopeia, the queen of Ethiopia, bragged that her daughter was more beautiful than the Nereids, sea nymphs blessed with incredible beauty." - the last clause could use clarification, such as "...Nereids, which are sea nymphs", or something.
  • You have to redlinks in the "History and mythology" section. Are you sure you can't link them anywhere?
    • I can't find anything for the Persideae and I feel like there should be an article for the Oracle of Ammon. There are a bunch of sources I could find with just a Google search. However, I don't really have the time to take that on. I could definitely link it to the Cult section in Amun if you'd like, or the Oracle at Siwa section in Zeus, or Siwa Oasis. What do you think?
  • In the second paragraph in "History and mythology", can you find a way to avoid saying "constellation" three times in two sentences?
  • "Part of Andromeda and most of Lacerta were taken in 1787" - how could it be taken? It sounds like territorial, but they're stars.... Again, this is why some explanation of what a constellation is (instead of just wikilinking it), could be helpful.
    • Rewritten to say "Several stars from Andromeda and most of the stars in Lacerta were combined in 1787". Would some writing earlier about how constellations are now also defined as specific regions of the sky, not just figures, help?
  • Is there any more history of Andromeda?
  • What does the m represent in 2.06m in the description of α And (Alpheratz, Sirrah)?
    • It's a symbol representing the visual magnitude; I don't think it's always necessary as I've not seen it in any of my sources. I removed it from β And's description too.
  • β, δ, ξ, and n descriptions appear to be unsourced.
  • What is an arcsecond?
  • "δ And is a 3rd magnitude star." - that's a different format than the other ones. How come?
  • What does " F-type dwarf" mean?
  • Watch for overlinking of binary star
    • Delinked a bunch.

I'll take care of more comments later once you address some of these. --♫ Hurricanehink (talk) 22:12, 28 April 2012 (UTC)[reply]

Thanks for your review! I look forward to more comments. Keilana|Parlez ici 22:03, 29 April 2012 (UTC)[reply]

Part Two: The Return of the Editing (rated PG for pretty good... so far)

  • "The Great Galaxy" - I notice this a few times. Is that the official nickname? You mention it in "Deep-sky objects" as if you had established what it was, but it's left there with some ambiguity. Could you explain it in the article?
  • " It is an enormous barred spiral galaxy - 192.4 by 62.2 arcminutes[4] - much like the Milky Way" - I'm confused what part is like the Milky Way. The previous sentence said that the galaxy is twice the size of the Milky Way.
  • "The Andromeda and Milky Way galaxies also have a shared destiny: in about five billion years, the two will begin a massive gravitational interaction - also called a "collision" - that will spark extensive new star formation" - this part is cool, but the way it reads sounds like it will definitely happen. You should add "predicted" somewhere in there. ("the two are predicted to begin", something like that). The shared destiny part sounds a bit dramatic, IMO.
  • "M110 is classified as either a dwarf spheroidal galaxy or simply a generic elliptical galaxy." - why either/or?
  • "Andromeda's most celebrated open cluster" - ehh, celebrated?
  • I notice you don't explain why the constellation is only visible from the northern hemisphere of Earth (unless I'm mistaken). It might be obvious, but how come?
    • Well, it lies sorta close to the north celestial pole, which is what's directly overhead when you're standing at the North Pole. So the farther you get away from the pole, the more stuff to the south you see. But the flip side of that is that the pole dips closer and closer to the horizon, until when you're on the equator, both celestial poles are on the horizon and you can technically see anything except for the pole stars. Andromeda is actually visible up to 40 degrees of latitude south, but it's to the north of the celestial equator, so it's considered a northern constellation. Does that help?

I think that's it! --♫ Hurricanehink (talk) 22:15, 1 May 2012 (UTC)[reply]

K, just a few small things and I'll be happy to pass it! ♫ Hurricanehink (talk) 14:03, 2 May 2012 (UTC)[reply]
Yay! Thanks for your thorough review...I'm a little nervous about FAC though. Keilana|Parlez ici 22:31, 2 May 2012 (UTC)[reply]
