I find "It is located at a distance of about 8 kiloparsecs in the brightest part of the Milky Way, in the direction of the constellation Sagittarius" confusing, but I'm not sure how to clean it up. One step forward would be to indicate that the distance is from earth, and it's probably better to use light years instead of kiloparsecs. Could somebody who knows more about astronomy take a swing at it? Thanks! -- William Pietri 08:15, 3 November 2005 (UTC)
Recent papers give a much larger uncertainty in the distance to the galactic center, e.g. 8.4 +/- 0.6 kpc ( http://arxiv.org/abs/0902.3913), and even a range as large as 6-10 kpc ( http://arxiv.org/abs/0907.4685). I don't agree with the above comment of using light years rather than kpc, since kpc is the natural unit for galactic sizes. Jcline1 ( talk) 21:15, 29 October 2009 (UTC)
Why not give figures for both light years and kpc? As a general reader the sentence " It is located at a distance of 8.33±0.35 kpc (~27,000±1,000 ly) ... " is utterly meaningless to me. I find this a problem with other entries on astrophysics. I want to know things like - how big is the galaxy? where are we located in it? how far is it to the centre? to the edge? etc. Simple stuff ... the stuff I expect to find in an encyclopaedia, rather than a scientific paper.
I predict that the opening paragraph means nothing to 99.9999% of Wikipedia readers.
(For that matter, what are ly? kpc? how about a link for them? I'm not against learning new notations etc., but I don't want to have to learn them to understand a wiki entry.)

The name of the Milky Way's galactic center is the Shapley Center. I just added a redirect so that name redirects here. However, the name of this article should be about galactic centers in general. For instance, does the center of Andromeda Galaxy have a name?-- Will 05:17, 14 August 2006 (UTC)

that's funny, because i came to this article looking for astrological crap, ie the mayan calendar coinciding with the alignment of the sun and galactic center in 2012. if it doesnt belong here, can there at least be a link to the info located elsewhere? 76.217.120.247 15:58, 6 July 2007 (UTC)

If you really want to look up astrological information, try http://en.wikipedia.org/wiki/Portal:Astrology. Not an astronomy article. Metaphysically ( talk) 08:53, 30 April 2008 (UTC)
The second half of the article stated unequivocally that there is a black hole at the Galactic Center. The first half qualified this, and implied that there might not be.
There is a published article in the journal Nature that states there is no doubt that there is a black hole in the center. I edited this article to reflect that certainty. At this point (six years later) there are numerous confirming articles.
Any editor who wishes to change that must cite a reliable reference.

There are two good pictures (specifically this one and this one) that could be very useful within this article. However I've not been able to fit them without changing the aspect of the article too much. Someone else with a greater sense of order could do it.-- ElPeski ( talk) 23:42, 12 April 2009 (UTC)
Might there be something surrounding the core? In spore, there are The Grox, and they try to let you not go through to it. Is the great rift a clue in to something preventing us from seeing the center or something? DownAirStairsConditioner ( talk) 15:15, 22 August 2009 (UTC)
It seems more logical to me that the 'c' should not be capitalized. I'd be hard convinced that this is a proper name. __ meco ( talk) 13:46, 5 April 2010 (UTC)

I removed this text:
"even if that were true [that there is no density cusp] for the Milky Way's Galactic Center, realistic models of how stars distribute around massive black holes have shown that regrowth of the cusp would take place in a time shorter than the Hubble time"
In other words: we should believe someone's theoretical models, rather than the observations. The observations do not show a cusp, and it is silly to say that "the cusp must be there because my models predict it"! — Preceding unsigned comment added by 12.22.214.242 ( talk) 15:37, 14 August 2013 (UTC)
I am proposing that Great Annihilator be merged into Galactic Center, as currently the GA article is one sentence long (and I can't see it getting much larger based on the research I've found). In my opinion it doesn't need a page to itself unless a major discovery happens. Primefac ( talk) 16:34, 8 May 2014 (UTC)
The first paragraph mentions "1 Giant Dark Matter Star with 82 Huge Dark Matter Satellites" with no citations at all. Never even heard of anyone proposing such a weird setup. This sounds like another reference to Star Trek or perhaps Captain Future phantasmagoria. Recommending deletion. There is a T101 in your kitchen ( talk) 15:05, 1 October 2016 (UTC)

I think it would be good to add info from this study to the article (it would probably need a new section). It's currently featured briefly in 2021 in science like so:
Astrophysicists report the discovery of unexplained blockage of high-energy cosmic rays entering the Galactic center, such as a strong magnetic field. [1] [2]

Galactic Center →
Galactic center – Looking at scholarly sources, the usage is split (outside of the titles of papers) between "Galactic Center" and "Galactic center" (see
this arxiv search, for example). Since there does not seem to be a consensus that the word "center" is part of the proper name, we should default to
WP:NCCAPS and not capitalize subsequent words in the title. --
