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)[reply]

"'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)[reply]

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. Casliber (talk · contribs) 22:23, 16 October 2010 (UTC)[reply]

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)[reply]

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)[reply]

Thank you again Casliber.—RJH (talk) 18:34, 10 December 2010 (UTC)[reply]
