ITN discussion - New Link (4/16/2022)
If interested - a discussion is considering presenting "HD1 (galaxy)" as an "ITN news note" at => "In the news/Candidates/April 2022" - editors are more than welcome to present their views and comments of course - iac - Stay Safe and Healthy !! - Drbogdan (talk) 23:00, 8 April 2022 (UTC)

"Oldest" galaxy
Just want to raise a clarification, since this is widely reported by the media. Because this galaxy is right at the end of the reionization era end of the Dark Ages, the era where the first stars are still forming, isn't it more correct to say that this is the youngest galaxy we have observed, rather than "oldest"? We are looking at a galaxy that is 70 million years old, at least its observed light. And it would be incorrect to assume that this galaxy still exists as of the present day. We don't look at a childhood photo of the oldest human and describe that this is the oldest human we have ever recorded. SkyFlubbler (talk) 02:27, 9 April 2022 (UTC)
 * ✅ - I agree. I have changed it to "most ancient". Alexcalamaro (talk) 08:06, 9 April 2022 (UTC)
 * Wait wat... isnt that the same as oldest? · · · Omnissiahs hierophant (talk) 08:28, 9 April 2022 (UTC)
 * ✅ - seems the word "earliest" may be better - text now adjusted in the main HD1 article - also, for support of the word adj, see my related => "Template:Nature timeline" (see copy on the right) - iac - Stay Safe and Healthy !! - Drbogdan (talk) 12:26, 9 April 2022 (UTC)

Right ascension and Declination of HD1 and HD2
In this article there are descriptions HD1 (10:01:51.31 +02:32:50.0) and HD2 (02:18:52.44 -05:08:36.1). Are these expressions common in the astronomical community? If not, is it possible to add RA and DEC to them with links to Right ascension and Declination like HD1 (RA:10:01:51.31 DEC:+02:32:50.0)?―― Phoenix7777 (talk) 09:53, 9 April 2022 (UTC)
 * ✅ - (and others) - Thanks for the suggestion - yes - *entirely* agree - added suggested edit to the "HD1 (galaxy)" section - adding to the infobox may be ok for HD1, but not as well for HD2 I would think, since the article features HD1 (and only secondarily HD2) - however - flexible with this of course - iac - Stay Safe and Healthy !! - Drbogdan (talk) 12:16, 9 April 2022 (UTC)

It would be better off to just remove them and leave it as a data in the infoboxes (as for all hard numerical data). We should just, however, describe what constellation are they located to simplify stuff. SkyFlubbler (talk) 10:08, 9 April 2022 (UTC)

Attention from expert
Considering the vital importance of these old galaxies at determining how the early universe formed, which is exciting in itself, this galaxy may shed light on earlier star formation as well. I am surprised at the lack of attention this article is getting, although it is being edited and viewed by a few I would have expected far more attention. Considering its importance I think it should be looked at by someone with more qualifications than I do. Space pierogi (talk) 16:01, 11 April 2022 (UTC)

Photometric, not Spectroscopic
The article incorrectly lists HD1's spectroscopic redshift as 13.27 - this the estimated photometric redshift, not the fsr more accurate spectroscopic redshift. As far as I'm aware HD1 is still awaiting spectroscopic confirmation by the JWST, as noted in the article further on. 2A02:C7D:A901:CC00:ED61:EBE7:F976:E36F (talk) 01:13, 18 August 2022 (UTC)

HD1 (galaxy) → HD1 – There is no need for a disambiguator, since HD1 already redirects here. 117daveawesome (talk) 07:46, 20 November 2023 (UTC) The discussion above is closed.

 * Support or possibly disambiguate with Euro1080 which was formerly the target of the rediret though the galaxy appears primary based on Google.  Crouch, Swale  ( talk ) 17:46, 20 November 2023 (UTC)
