Punctuation separators

In the list of events and discoveries, there is a lack of consistency in the punctuation separating those items.

Some end with a period, some a comma, and some have no punctuation at all !

Myself, I lean toward the ‘period approach.’

Any guidelines or perspectives here ?

TIA.

The link "IRAS_F10214+4724" is not understood by Wiki. Tabletop 10:16, 31 Mar 2005 (UTC)

Those were replaced by IRAS F10214 plus 4724 back when we had that technical limitation, but now "plus signs" work in names, so IRAS F10214+4724 can exist as an article name. 76.66.197.30 (talk) 14:22, 24 September 2009 (UTC)[reply]

Hello, just to tell you that this has been translated into french. And to thank you to all the contribvutors of the origninal in EN:. Hop ! Kikuyu3 (talk) 16:56, 1 July 2010 (UTC)[reply]
PS : Now I'm in search for another page to translate with an even longer title.

Unbalanced

Although this timeline seems mostly very reasonable, the entries referring to Gudehus seem like vanity editing. These contributions are real, but not of the same level of significance as the rest of the timeline. — Preceding unsigned comment added by 128.189.202.215 (talk) 22:39, 6 September 2011 (UTC)[reply]

External links modified (January 2018)

Hello fellow Wikipedians,

I have just modified one external link on Timeline of knowledge about galaxies, clusters of galaxies, and large-scale structure. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Added archive https://web.archive.org/web/20060209145355/http://www.news.wisc.edu/11405.html to http://www.news.wisc.edu/11405.html

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

No special action is required regarding these talk page notices, other than regular verification using the archive tool instructions below. Editors have permission to delete these "External links modified" talk page sections if they want to de-clutter talk pages, but see the RfC before doing mass systematic removals. This message is updated dynamically through the template {{source check}} (last update: 5 June 2024).

Eligibility of study "Web of the giant: Spectroscopic confirmation of a large-scale structure around the z = 6.31 quasar SDSS J1030+0524"

Should information about this study be added to the timeline? Are there other articles to which information about it should be added? It's currently featured in 2020 in science like so:

Astronomers announce spectroscopic confirmation of a web-like structure containing galaxies and dark matter around, and likely fueling, a quasar at an age of the Universe of 0.9 bn years, which contributes to an explanation of how such supermassive black holes could have grown rapidly so early.^[1]^[2]^[3]

From the study:

Our finding lends support to the idea that the most distant and massive black holes form and grow within massive (>1012 M⊙) dark matter halos in large-scale structures and that the absence of earlier detections of such systems is likely due to observational limitations.
