Okay, I'll make straightforward copyedits as I go and post queries below. Please revert if I change meaning inadvertently. Casliber (talk · contribs) 03:37, 14 September 2010 (UTC)

"'This is the largest and brightest galaxy within the northern Virgo Cluster, located about 55 million light years away from Earth - the way it reads, it isn't clear whether M87 or the Virgo Cluster (or both) is what is 55 million light years from earth. "  Done

"Messier 87 galaxy has no distinctive dust lanes... - do we need the "galaxy" here? Not written as such elsewhere.  Done

This identification was confirmed by 1953 - odd wording. You mean "The soruce was confirmed as coming from M87" (?)  Done, reworded.

The only known visual observation of the jet was by Russian-American astronomer Otto Struve using the 254 cm (100 in) Hooker telescope - how/why?

and may indicate that the black hole has been accelerated by the jet - I don't follow - you mean "moved" or "displeced" or ..what?

The Virgo Cluster section could be expanded a little - M87's role in it, closest neighbours etc.

Okay - typing "Messier 87" into the Web of Science search engine yields the following:

Why on Earth would you run such a search? For a start, the astronomy databases (ADS, SIMBAD, NED) are far more sensible places to look than WoS. Secondly, there are thousands of papers on M87. Here is a straightforward ADS object search, which found 4238 papers. Even restricting the search to only papers with 'M87' or 'Messier 87' in the title (let alone the abstract) leaves 913 papers [1]. Good luck digesting all of those!

(belatedly) I have used WoS for biology articles, my usual area of editing on wikipedia. I am a bit of a neophyte on astronomy articles. But in any case, all of these show some other material worth looking at. Casliber (talk · contribs) 21:55, 16 October 2010 (UTC)

Images are provided where possible and appropriate, with suitable captions:

Overall:

Pass or Fail: -I think the best thing is to let this nomination slide for the time being as there is no movement. I am actually interested in doing it myself but can't see that happening for a monht or two, so maybe I will wokr on it and nominate it myself sometime.

Thanks for the review Casliber. I'm unclear why it was nominated if there was no interest in correcting the issues.—RJH (talk) 18:28, 18 October 2010 (UTC)

PS: As a postscript, I think the concerns I raised are fixed now. As I haven't done any active editing. I'm happy to take a closer look and review when put up again. I'll try and give it a shove toward FAC if I can and look to think what else might be of help. Casliber (talk · contribs) 20:21, 8 December 2010 (UTC)
