Images by Scott Sheppard
At S/2004 S 24, the infobox image was deleted at Commons due to copyright concerns — Sheppard is not employed by NASA. This raises concerns about many other images taken by Sheppard of irregular moons in the Solar System, though non-free images would qualify for inclusion at the moons' infoboxes per WP:NFCC if there is no NASA-created equivalent. –LaundryPizza03 ( d c̄ ) 17:35, 10 August 2023 (UTC)

Clickable constellation links
Most constellation entries end with an External Links section that includes a link called "the clickable [constellation name]". These go to a domain named . Currently that site is returning a "not available" flag. I noticed it a few days ago; when the link actually went dead I do not know. Perhaps one of you has already noticed it. It is not clear whether this is a hosting problem and the site will return, or whether the site has disappeared for ever. Three options occur to me: 1, wait to see if it reappears; 2, delete all links as being dead; 3, change the link to an archive version. Thoughts? Skeptic2 (talk) 13:02, 11 August 2023 (UTC)
 * When a link is presented via a citation template, there's a bot that will update it to point to a Wayback Machine archive. I'd say that's the default solution. Praemonitus (talk) 14:22, 11 August 2023 (UTC)

RfC regarding Stephenson 2 DFK 1
I am raising this discussion here to get more attention.

This has been a very long (probably 2 years now) dispute regarding the radius of this star, which has been controversial and the reasons for consensus are invoking WP:NOTRIGHT (which I do take a lot of issues with, see the discussion regarding this issue).

This has become a hot mess to deal with that I think this needs to be raised here on the Wikiproject proper. I highly recommend you to check and contribute to the discussion. SkyFlubbler (talk) 05:53, 20 August 2023 (UTC)

Turn abandoned wikiprojects into task forces
The Wikiprojects Solar System, Mars, Moon and Eclipses are largely abandoned. What if we turn them into task forces? Cambalachero (talk) 01:17, 26 July 2023 (UTC)
 * I support that. We already have task forces for Constellations, Cosmology, and Jupiter, so the precedent is there. I'd also be in favor of merging the WikiProject Astronomy and WikiProject Solar System templates. Praemonitus (talk) 01:40, 26 July 2023 (UTC)
 * Yes, that would be part of the change. WikiProject Council/Guide/Task forces explains in detail the difference between standalone wikiprojects and task forces. Cambalachero (talk) 02:19, 26 July 2023 (UTC)
 * Thanks. So what would we do about article talk pages that have both astronomy and solar system WP templates? We'll need to merge their parameter settings. Praemonitus (talk) 21:34, 26 July 2023 (UTC)
 * Yes, we would need to merge both templates so that they show the same thing and use the same parameters (or make one a redirect to the other). The best way to remove duplicate templates from talk pages would be using a bot. Of course, this is something that should only be done if we get consensus for all this and some time has passed so that anyone interested may know about it (a week perhaps?) Cambalachero (talk) 02:45, 27 July 2023 (UTC)
 * I've done it before, it's pretty straight-forward. Can't remember if there's a dedicated bot for it these days but if not I can handle the technical side of this. Primefac (talk) 07:33, 27 July 2023 (UTC)
 * Support Parham wiki (talk) 07:30, 26 July 2023 (UTC)
 * Support Uncontroversial proposal. –LaundryPizza03 ( d c̄ ) 17:28, 10 August 2023 (UTC)
 * I've started updating astronomy to accommodate the new task forces. If someone else feels motivated (it's very low on my priority list) we'll need to shift over the various "WikiProject X" pages to "Taskforce/X" subpages (see for example Jupiter). Primefac (talk) 08:12, 16 August 2023 (UTC)
 * Should we also merge Category:WikiProject Solar System participants (92 pages) and Category:WikiProject Astronomy members (302 pages)? Renerpho (talk) 20:34, 22 August 2023 (UTC)
 * I was planning on updating all of the various categorisation after I was done with the template mergers (e.g. content related to Category:WikiProject Solar System articles), but that's a good point. I think changing the category name to "Solar System taskforce participants" or similar would probably suffice - we don't want to necessarily assume that someone in the SS project necessarily must be in the AST project. Primefac (talk) 10:56, 23 August 2023 (UTC)
 * That should work, but please note that there is Template:User Solar System Coordinator, while WikiProject Astronomy has no equivalent batch. Renerpho (talk) 07:51, 24 August 2023 (UTC)

Naming consistency
Okay, so I've started moving things around, and I've noticed some inconsistencies that I want to sort out (mainly so I don't have to shift things twice). For our taskforces, are they "X Task Force", "X task force", or "X taskforce"? All three are valid, and I believe I have seen all three in the wild, but we should probably pick one and stick with it (for example, the first line of the Mars Task Force says "The Mars taskforce", which is an annoying inconsistency). Primefac (talk) 09:53, 29 August 2023 (UTC)


 * It would seem from Category:WikiProject task forces that most use "Name task force". Gonnym (talk) 09:02, 30 August 2023 (UTC)

Duplicated lists?
There is a featured List of space telescopes, and additionally List of X-ray space telescopes and List of proposed space observatories, both looks to be duplicates of sections of the first list. Should they be merged into the main list? I see no good reason to have three lists (two of them mostly unsourced) instead of good-sourced and well-organizes one list that we already have. Any thoughts on this? Artem.G (talk) 19:32, 29 August 2023 (UTC)
 * Per WP:SPLIT, List of X-ray space telescopes may be a child of List of space telescopes: it's used that way in the latter. But yes some type of reconciliation would be good. Praemonitus (talk) 14:29, 30 August 2023 (UTC)
 * but why this child list is needed if the main one still has a section for X-ray telescopes? Basically it's a duplicate with less info and with few more (unsourced) entries than in the main list... Artem.G (talk) 16:51, 30 August 2023 (UTC)
 * I can't think of a good reason. Perhaps this needs to be asked on the article talk page? Praemonitus (talk) 16:33, 1 September 2023 (UTC)

Removal of Influences/influenced from the scientist infobox
hey, here's a proposal to remove Influences/influenced fields from the scientist infobox. It was done for the philosopher infobox, and bacause these fields often have too many unsourced / unnecessary entries never covered in text it might be a good idea for scientists as well.

Inviting suggestions for Wikipedia training sessions
In the next couple of months I will be helping to run some training sessions on behalf of WMF(UK) for members of the International Astronomical Union and Max Planck Institute on how to contribute to Wikipedia. I would like to invite WikiProject Astronomy members to submit any suggestions of points specific to this field that I ought to be aware of, or to raise during that training; any pitfalls professionals need to avoid, or pointers to identifying key topics for improvement or creation. Any other ideas, concerns or suggestions are also welcome. My rough notes to date on planning these sessions can be found at User:Nick Moyes/training. It includes a Google slides presentation that I plan to use, which is also under construction. Many thanks, Nick Moyes (talk) 21:32, 16 August 2023 (UTC)
 * Thanks. Praemonitus (talk) 21:50, 16 August 2023 (UTC)
 * This might be related. The content of astronomy articles should be specific to the object and not sway too far out of the topic. See this previous version of Abell 1413, which has been an article chosen for a Wiki Education Foundation-supported course assignment; the article has since been changed to better suit an encyclopedic tone. SkyFlubbler (talk) 23:33, 20 August 2023 (UTC)3]]


 * Thanks for your efforts. Please ensure that your trainees are aware of WP:NASTRO, WP:NCASTRO and WP:COI. Often scientists try to start editing by writing an article about themselves, an object they discovered, or a broader topic that they are a primary source for. Those run into notability and conflict of interest problems. It's better to work on something that's close enough to their expertise that they understand the science, but far enough that they haven't worked on it directly themselves. Modest Genius talk 11:25, 1 September 2023 (UTC)
 * Thanks, SkyFlubbler and Modest Genius. I took your suggestions on board for my presentations given earlier this week. (My apologies for the delay in acknowledging your feedback). Our audience were mostly astronomy educators, rather than cutting edge scientists, but COI was nevertheless explained. It's possible that the IAU's NAECs might want WMF(UK) trainers to develop further sessions on using Wikipedia's astronomy content for teaching young people. So I may well come back for further advice and suggestions from you folks later on!
 * I sent all participants whose usernames we managed to capture a bespoke welcome message, which you can see at the top of this page. Regards, Nick Moyes (talk) 23:48, 5 October 2023 (UTC)

Computational Astrophysics/Cosmology
Not so long ago I noticed that the computational side of astrophysics and cosmology on Wikipedia is extremely incomplete and lacks several articles, templates, and maintenance in general. (Latter is not surprising as the Cosmology task force is inactive...) As someone, who's doing a PhD in this field, it was really surprising to me, since computational aspects of both fields are increasingly vital in astronomical research.

I noticed there is a Computational astrophysics article that writes a couple words about cosmology too, however it's far below the bare minimum. While there's a certain overlap between these two topics, I feel a definite difference should be made between astrophysics and cosmology and Wikipedia should also reflect that.

For this reason I have a couple propositions:
 * 1) I would happily start writing a base for Computational cosmology and collect all closely related and existing (and non-existent, but important) articles into a series and maybe create a template sidebar for them, similarly to that of Template:Physical cosmology.
 * 2) Create some important, but non-existing articles mentioned in the previous point, e.g. widely used cosmological software like GADGET, GIZMO, PKDGRAV, etc., as well as cosmological suites, like the Millennium Run and the Simba project.
 * 3) Clean up references to articles at "wrong" places, like a random reference to the Illustris project (a cosmological simulation suite) under the "Experiments" list of Template:Physical cosmology and similar anomalies.

But first, I wanted to ask the community's opinion about any of this. While I see this topic is extremely important and vital in astronomical research nowadays, others may have a different opinion on the relevancy of this topic specifically on Wikipedia. Or, some may have some alternative solutions to my original problem statement.

-- Masterdesky (talk) 15:55, 26 October 2023 (UTC)


 * Sounds like a good idea. Wikipedia's science articles tend to be written either by very enthusiastic amateurs, or whatever professionals happen to have time, so random areas are missing coverage just because nobody with a relevant background wrote anything. Please go be WP:BOLD! - Parejkoj (talk) 16:49, 26 October 2023 (UTC)
 * Great idea, and it's always good when real experts write articles about their field! Artem.G (talk) 17:47, 26 October 2023 (UTC)

How should I create article(s) for the asteroid pair (458271) 2010 UM26 and 2010 RN221?
I want to create an article for the asteroid pair and, but they have very similar orbital elements (down to several decimal places) and have only been studied together in publications (examples: (MPML)(Vokrouhlický)(Jewitt 2023)). Should I create a single article that includes both objects (title will be " (458271) 2010 UM26 and 2010 RN221") or should I create two separate articles for (458271) 2010 UM26 and 2010 RN221 individually? Not much is known about the individual asteroids other than their approximate sizes, shapes, and orbits; the biggest point of scientific interest is their very similar orbits and separation history according to the publications I listed earlier. Thanks. Nrco0e (talk) 07:31, 5 November 2023 (UTC)


 * I think that one article for similar objects makes more sense, if both are almost always described together. Artem.G (talk) 08:07, 12 November 2023 (UTC)
 * I agree with that too, though the single article name is quite long and tedious with all these numbers. Can't really avoid that unfortunately, but I guess that'll do. Nrco0e (talk) 15:47, 12 November 2023 (UTC)

IAU MPC API URL?
Can anyone share an example URL request for the MPC's API, if it exists, or point to a resource describing such? They seem keen on having you go through python or some other interface, but I just want to scrape HTML the old fashioned way. I'm specifically looking for "Orbit type: Hilda", etc., which can be found here: 625000, but not here:, nor here (JPL's API). I realize I can constrain the orbital elements myself, but would rather not have to do that for all the various orbit types. ~ Tom.Reding (talk ⋅dgaf) 03:34, 12 November 2023 (UTC)
 * would one of yall be able to help?  ~ Tom.Reding (talk ⋅dgaf)  17:30, 12 November 2023 (UTC)
 * Currently the HTML code shows the forms are using the "get" method, so you should just be able to call the site's "/db_search/show_by_orbit_type" script with the appropriate parameters added. Just do a ctrl-u on the lookup page to see the HTML. Does that answer your question? Praemonitus (talk) 23:15, 12 November 2023 (UTC)
 * I'd rather not use their web/human-readable link https://minorplanetcenter.net/db_search/show_object?object_id=625000, since I want to query at least 10,000 objects for now, and even more later. I've been temporarily blocked before for exceeding either their request-frequency threshold, or a time-averaged request count limit. A machine-readable API would have much higher thresholds that I wouldn't have to worry about as much.  ~ Tom.Reding (talk ⋅dgaf)  01:59, 13 November 2023 (UTC)
 * I have no information about their API, and I'm not sure if they would want to expose it. Praemonitus (talk) 03:13, 13 November 2023 (UTC)

Authority control on minor planets?
What do we think of adding, , and other relevant identifiers to the Authority control template, in either the existing AC section "Other", or in a new section called "Scientific"?

JPL small body, NeoDys, and other templates exist, but they each require separate placement on each page, while Authority control would be able to capture all current and future database inclusions, and automatically display them compactly at the bottom of the page. I'm not suggesting Authority control replace JPL small body, etc., since they provide much more info, but that Authority control be used regardless.

Infobox change
There is a discussion about changing infobox colours for planets. Please join in the discussion here. Primefac (talk) 20:43, 13 January 2024 (UTC)

Choosing a standard img size for infobox planet
1400+ articles (mostly asteroids, but also some comets, moons and TNOs) still had the infobox img size set locally from years ago when that was necessary. Mostly the number was just copied over from the sample box, which was at various times set from 250 to 265 px -- that is, they were mostly cruft. I stripped most of them out so that the template default size would be used. A question though is what default size would work best. I assume we'd want something almost the width of the info box; i.e., as big as possible without causing the info box to take up more space, but also accommodate ppl with vision impairments by sizing the img relative to the reader's pref rather than absolute pixels, which is deprecated for accessibility reasons. Scaling at 1.33 seems to work well. Is that okay? — kwami (talk) 22:26, 14 January 2024 (UTC)

Redundant planet topics
We now have articles for mega-Earth, super-Earth, and sub-Neptune. They seem a bit redundant. Praemonitus (talk) 16:59, 26 January 2024 (UTC)


 * In sources that use both terms, super-Earth and sub-Neptune are mutually exclusive - a sub-Neptune is larger than a super-Earth. I could support merging mega-Earth into super-Earth, and sub-Neptune into mini-Neptune. SevenSpheres (talk) 17:19, 26 January 2024 (UTC)
 * Yes, merging would likely make them simpler to support and add some clarity. Praemonitus (talk) 01:21, 27 January 2024 (UTC)

Oppose merging Mega-Earths are more massive than super-Earths and indeed can be more massive than Neptune. Also sub-Neptunes are not necessarily anything like Neptune so are not always Mini-Neptunes. Some mega-Earths could be considered as Super-Neptunes and sub-Neptunes at the same time because they have a larger mass than Neptune but a smaller radius.

 * Sorry but your statement just further obfuscates the subject, at least for me. Do consensus opinions even exist? We do have a list of planet types article, which doesn't have separate rows for sub-Neptune or mega-Earth. Perhaps we could start there? It is very poorly cited. Praemonitus (talk) 16:13, 27 January 2024 (UTC)
 * That list also doesn't have rows for Super-Neptune or Super-puff or Ultra-short period planet or Ultra-hot Jupiter. Fdfexoex (talk) 16:38, 27 January 2024 (UTC)
 * I thought "super-puff" is a joke, but it seems to be a real term, used by NASA, and several real articles published in Nature. Artem.G (talk) 17:58, 27 January 2024 (UTC)
 * It would be handy if there were a mass (or size?) vs. density chart that divided up the various definitions, but I haven't been able to find one. Praemonitus (talk) 19:00, 27 January 2024 (UTC)
 * caltech says that "A super-puff is a planet with a super-Earth mass (less than 5 M⊕) but a gas giant radius (larger than 5 R⊕). If you plot them on a mass-radius diagram with other known exoplanets, they are clearly outliers. Their mean density can be as low as 0.1 or 0.01 gcm^-3 (similar to the density of cotton candy). This is one or even two orders of magnitude lower than most exoplanets", and they have a mass/radius plot. Artem.G (talk) 20:12, 27 January 2024 (UTC)
 * To my knowledge, a tentative consensus exists wherein a super-Earth is relatively volatile-poor (and therefore more "Earthlike," I guess) whereas a mini/sub-Neptune is more volatile rich and generally compositionally similar to the ice giants of our Solar System. Of course, no formal definition exists and our knowledge of specific exoplanets is often very poor; I will also put out a disclaimer that exoplanets are far from my strength. However, from what I have seen, the two categories do carry different (albeit informal) connotations when used in scicomm and in literature. ArkHyena (talk) 07:55, 30 January 2024 (UTC)


 * Unfortunately, there is no consensus on the use of these terms, even among experts. Different researchers use different terminology for the same objects. I think most agree that super-Earths and sub-Neptunes are separated by the radius valley, but there's even debate on whether the radius valley is a real thing or just a projection of a 'density gap'. The other terms do not have widely accepted definitions; each group or study states its own definition, or simply uses the terms without definition. It's a real mess, that will probably take researchers a decade to sort out. Maybe we should have some form of overview article, types of exoplanet or similar, where these issues could be discussed? <b style="font-family: Times New Roman; color: maroon;">Modest Genius</b> talk 12:40, 31 January 2024 (UTC)

Proposed deletion of Cis-Neptunian object


The article Cis-Neptunian object has been proposed for deletion&#32;because of the following concern: "This classification is seldom used by researchers, does not appear to be a consensus classification, and is largely redundant. On NASA ADS, only one search result for 'cis-Neptunian object' is relevant to the term, out of four total results."

While all constructive contributions to Wikipedia are appreciated, pages may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the page to address the issues raised. Removing will stop the proposed deletion process, but other deletion processes exist. In particular, the speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion.

Remaining pictures uploaded by Celestialobjects
Even after an arduous admin review and mass deletion about a year ago I am quite surprised that there are still a lot of pictures uploaded by this guy that are still used in many articles, like the Hercules–Corona Borealis Great Wall, Giant GRB Ring, Saraswati Supercluster, and U1.11, of which I have all removed from the articles.

Apparently, the mass deletion review did not heed Nrco0e's (another user that I also see some works being problematic) request of deleting all of this user's uploads, and so we still see a LOT of his misleading pictures. Keep in mind that even after all of this, he still uploads a lot of planet images as late as, eight months after he was apprehended, which I am almost certain is made using a software like Universe Sandbox, of which he has not linked in the description.

A bit of help to remove the images uploaded by this guy to various astronomy articles, as well as to launch another mass deletion of his uploads in Commons that somehow got missed, to finally remove all the images lacking scientific merit once and for all.

Norma cluster vs Norma Cluster?
I thought perhaps "Norma" was a cluster, so Norma Cluster should be named Norma cluster according to WP:NCCAPS. But I've found sources that used "Norma Cluster" and other that use "Norma cluster". So perhaps the proper name of the thing is "Norma Cluster"? Is there any astronomical naming convention source that says one way or another? Johnjbarton (talk) 17:17, 11 February 2024 (UTC)


 * Yes, "Norma Cluster" should be capitalized as a proper name. Norma is the name of the constellation it's in, like the Virgo Cluster or the Andromeda Galaxy. SevenSpheres (talk) 18:40, 11 February 2024 (UTC)
 * Thanks. Do you know of any sources that discuss this convention? Johnjbarton (talk) 18:47, 11 February 2024 (UTC)


 * SevenSpheres is correct. The phrase 'Norma cluster' (a common noun) could refer to any cluster of stars or galaxies located in the constellation Norma. The 'Norma Cluster' (a proper noun) refers to a specific galaxy cluster. Any book on English grammar or style will confirm that proper nouns are capitalised, and our MOS agrees. For a more Earthly comparison, compare 'a Washington monument' to 'the Washington Monument'. <b style="font-family: Times New Roman; color: maroon;">Modest Genius</b> talk 14:32, 12 February 2024 (UTC)

Stellar mass limits
It was my understanding that the Chandrasekhar limit concerns the maximum mass at the process of a star -> white dwarf transition. The end point is stable so the story ends.

Is Tolman–Oppenheimer–Volkoff limit really analogous, meaning the max mass for star -> neutron star, end of story?

(I'm not really interested in the fine points of how these limits might be changed by better models, but rather just the concept they represent; these pages get edits that want the end points and cross the limits).

Ideal would be a ref. Johnjbarton (talk) 02:10, 21 February 2024 (UTC)


 * Yes, that is my understanding too. Here's a possible ref. that discusses both limits:
 * Praemonitus (talk) 06:06, 21 February 2024 (UTC)
 * Thanks, I made changes to both pages using that ref. Please check. Johnjbarton (talk) 16:10, 21 February 2024 (UTC)
 * I believe the first sentence of the "Tolman–Oppenheimer–Volkoff limit" section on the Chandrasekhar limit article is inaccurate. Praemonitus (talk) 18:28, 21 February 2024 (UTC)
 * Any hints on what you think is inaccurate? The sentence is:
 * Hydrogen-burning stars heavier than the Chandrasekhar limit continue to compress, overcoming the electron degeneracy pressure.
 * Johnjbarton (talk) 18:38, 21 February 2024 (UTC)
 * Well the exception applies to the degenerate cores of massive stars, not hydrogen-fusing stars that have a little more mass than the Sun. See neutron star for example. Praemonitus (talk) 02:15, 22 February 2024 (UTC)
 * Hmm. I suppose that both limits are really models based on the final state stability. So the mass that they refer to is final state mass.
 * But in both cases the initial state is a massive star and that mass determines the final state right? You can't get to degenerate core of a massive star unless you start with a massive star. Some range of masses result in white dwarf, some in neutron stars, some black holes (and some not yet settled intermediate values). All of the end states are stable (absent eg binary).  What is the role of the degenerate core mass?
 * Or maybe you are objecting to "hydrogen-burning"? That's fair since my sentence implies a starting state mass limit which I think is not correct. Johnjbarton (talk) 02:42, 22 February 2024 (UTC)
 * Right. I wouldn't mention hydrogen fusion. Maybe "stellar remnant"? In type Ia supernova you can exceed the limit via a double white dwarf merger. If Tolman–Oppenheimer–Volkoff limit is at the low end of the estimates, two sufficiently massive white dwarfs could merge to form a neutron star. Praemonitus (talk) 03:11, 22 February 2024 (UTC)

Life_habitable_zones is WP:SYNTH?
Some further input on Life_habitable_zones would be useful: the page looks like a WP:SYNTH list, with names that don't necessarily appear in the references and no obvious reason why it couldn't just be folded into Habitable_zone. - Parejkoj (talk) 18:16, 22 February 2024 (UTC)


 * Honestly I think that article should be deleted. Someone has put a lot of work into writing up their own personal ideas, into what reads like an undergraduate essay. The term "life habitable zone" is not in widespread use by astronomers or astrobiologists. ADS shows no hits for that exact phrase, and Google Scholar shows only a handful of peer-reviewed papers, none in astronomy journals. The TLDR bulleted list is just describing a bunch of adjectives that people have tacked on to 'habitable zone', some of which are widely used and others that are not. I really don't see the point or value in it.

draft:list of smallest named extraterrestrial craters lemme know what y'all think. Arlo James Barnes 09:56, 1 March 2024 (UTC)


 * I don't understand the purpose in such a list. We already have List of craters in the Solar System and its various sub-lists (organized by body). Why would anyone want a list of the smallest among them? The only reference in that draft is a link to a database (about Mars, even though most of the entries in the draft are on the Moon), not anyone discussing the smallest named craters. I'm not convinced this meets WP:NLIST and WP:GNG (WP:NASTRO does not apply to surface features). <b style="font-family: Times New Roman; color: maroon;">Modest Genius</b> talk 15:21, 1 March 2024 (UTC)


 * Ah, good feedback; this is why I wanted to link it here. There are more Mars craters I haven't added yet, but sourcing and notability difficulties remain. As to why, it's just interesting to me that these are structures of a size that could be feasibly walked around by a person in a spacesuit, or roved around in a relatively brief time, or even spanned. Of course, no such thing has happened yet so can't be sourced. Arlo James Barnes 16:41, 1 March 2024 (UTC)
 * Seems to me your goal would be much more easily and correctly attained by adding a simple paragraph with one or two examples.

Trouble in the Serpens article
For some reason, in the Serpens article infobox there are two images depicting Serpens Caput. As Serpens is a constellation divided into two non-contiguous parts (Serpens Caput and Serpens Cauda), there are two images to represent the two parts, and there should be a third to represent both parts. However, the third image is already duplicating the image of Serpens Caput. On Wikipedia, we have this image which represents the constellation as a whole.

I tried to edit the article, but I couldn't replace the image. Apparently the images are predefined in. InTheAstronomy32 (talk) 19:39, 5 March 2024 (UTC)

25 B-mag arcsec−2 isophotal diameter
The subject phrase seems to be standard Astronomy lingo for a specific way of defining a galaxy diameter. I assume that this would be defined in an astronomy text. I have none. Any hints on a source for the definition?

Thanks. Johnjbarton (talk) 04:10, 8 March 2024 (UTC)


 * An isophote is a contour of constant surface brightness, measured in magnitudes per square arcsecond. Our article isophote cites Binney & Merrifield 1998 for the definition, which is a standard textbook (though I don't have a copy right now). The choice of which photometric filter (B-band in your example), and what number to draw the isophote at, are up to the study in question. Deeper observations can use a fainter magnitude level - your example of 25 is very faint. The diameter of the isophote is a purely observational property - it tells you how big the galaxy appears in the data, not anything physical about it. <b style="font-family: Times New Roman; color: maroon;">Modest Genius</b> talk 15:23, 8 March 2024 (UTC)
 * Regarding this very specific isophote, which is then established as D25, you may refer to the papers by Foqué and Paturel (1983), Paturel et al. (1987), and Paturel et al. (1991). These are quite detailed but to put it simply, it establishes it as a standard. SkyFlubbler (talk) 11:30, 11 March 2024 (UTC)

Andrea Ferrara
I am a little bit confused about Draft talk:Andrea Ferrara (astrophysicist) because a sourced page was moved to draft for what sounds like minor reasons that no other users visiting it pointed out (so they don't look critical). I usually don't add information unless it's on third-party sources so I am not going to add more content just because it's on an official website even if I know it's true.

So whoever wants to take care of it further, please do so. Alexmar983 (talk) 00:05, 24 March 2024 (UTC)


 * I have restored it to mainspace, please see my comments on the talkpage. It was a completely unnecessary move to draftspace. AusLondonder (talk) 00:11, 24 March 2024 (UTC)
 * AusLondonder thank you. I suspect that the reason of such strong action was that since I am not an autopatrolled user, some people assume they need to scrutinize my contributions heavily. However, I have been an editor here for years, so there is really no need to push so hard.--Alexmar983 (talk) 00:22, 24 March 2024 (UTC)

Just to be clear now User:Ldm1954 converted his request to this warning but this is not actually correct to me. I analyzed all sources for months, all other sources are almost from websites of university or institutions where he is actually working. I usualy do not add such content. It's fineI suppose for some of you, I agree that it's there but I focus mostly on content that it's also on third-party sources or peer-reviewed such as in publication. If User:Ldm1954 wants to be more specific and link here all sources he is referring to can add some of them if they are from a thirdpart.--Alexmar983 (talk) 00:35, 24 March 2024 (UTC)


 * So the information here is correct, below is what I pointed out to the editors about the main issues with Andrea Ferrara which was created directly to main page so came up for new page review.
 * "Please read WP:NPROF carefully. As a new page reviewer it is not my job to correct badly structured pages, this is your job. As a few points:
 * Notability is not inherited. Supervising a PhD is not relevant
 * Being on advisory committees is WP:MILL
 * Telescope hours is WP:MILL
 * None of his career is mentioned. According to the current page he never did a PhD (or even BS)
 * No awards mentioned
 * Wrong infobox
 * Nothing in the page demonstrates that he passes WP:NPROF.
 * I noticed that you edited the page to proper format, then reverted it back to inappropriate format.
 * Please look at (plus others comments on them):
 * Marc Davis (astronomer) which has problems
 * Martin Rees for a massive, well-structured page
 * Craig Hogan needs info box and sources"
 * IMHO this is exactly what Draftification is for, a page on a topic that will pass notability which is so poorly constructed that it needs a complete rewrite. AfD would be wrong.
 * N.B., to @Alexmar983, all academics must have sources for their faculty positions and, preferably for the BS & PhD. BS is often a commencement PDF, PhD's are often online. The university is a valid sources for their appointment, as universities are legally bound not to misrepresent so this is of a higher level. Many of these issues are, and continue to be discussed on WT:NPROF, and you can see what is done for others. Ldm1954 (talk) 00:53, 24 March 2024 (UTC)
 * User:Ldm1954 I understand that they are ok, but I put in articles only what is sourced by other parties. Otherwise, the risk of putting content just because it's on a website influenced by the subject is there. We can survive withour a detail of a Ph.D that can be accessd, it's much worse to open the door to this use as source. So I am not putting it there. Someone else here can, if it is considered so important, but not me. Still, I don't think it is. There is a stub template for that reason, you do not need anything else. The notability is still clear by accessig any bibliometric indicator and just taking a look at all mentions on national newspapers. In other words, your template simply states that it is a stub. I am fine with a stub, it is much more honest than using a personal webpage as a source. If there is a more robust source availale, I am the first to insert it. Plus, there is a wikidata item also for more factual details.
 * However, as I told you in the talk page instead of putting a template and provide long explanation, just add it yourself. it's the most efficient pathway--Alexmar983 (talk) 01:03, 24 March 2024 (UTC)
 * The issue was firstly it was an unreasonable move to draftspace, and not what WP:DRAFTIFY is designed for. Secondly, the rationale you gave for moving to draftspace was explicitly about formatting issues. 40 minutes later you raised other issues, only after I restored the article to mainspace. AusLondonder (talk) 01:12, 24 March 2024 (UTC)
 * That was a little bit odd. I mean, before doing anything at this point it's obvious that someone really wants to be sure what is the most important issue and there's nothing else. Still, to me this looks like a stub. It is not a stub because I am 'lazy'; it is in that state because I do not believe that the true value of this editing work lies in merely copying content from the official webpage. I have spent months reading online sources, utilizing only reputable national newspapers, other sources already established in other articles, and third-party sources. While the official page is of course accurate, my goal in writing this article is to go beyond that information – that is the free content I aim to provide. If anyone else wishes to add more, sure, but the reader is not naive. The stub template exists for that very reason, so strictly speaking, there is no need for the current warning. It's just... a stub.--Alexmar983 (talk) 01:49, 24 March 2024 (UTC)

 * As a general categorisation, sure. Primefac (talk) 17:21, 21 March 2024 (UTC)
 * I forgot "bottom" existed (and I clearly didn't follow the provided link to it); I was thinking "low" would suffice for these types of articles. Primefac (talk) 17:47, 21 March 2024 (UTC)
 * I think most of those could be 'low' if they're specifically about astronomy; 'bottom' is intended for articles which are of interest to the project but are not primarily astronomy content (pseudoscience, mythology, science fiction etc.). General science museums or programmes that contain only a small amount of astronomical content should be 'bottom', museums dedicated to astronomy can be 'low'. I see you recently added The Sky at Night as an example, but that's a bad exemplar because it has been historically influential on astronomy itself so probably merits a 'mid' rating, as does Cosmos: A Personal Voyage. Things like Wonders of the Solar System seem 'low' to me. <b style="font-family: Times New Roman; color: maroon;">Modest Genius</b> talk 17:26, 21 March 2024 (UTC)
 * Okay, so do planetariums really belong in the 'bottom' category then? Perhaps we should have a separate category for 'Education' on the importance scale page so we can better capture this category? Praemonitus (talk) 03:11, 22 March 2024 (UTC)
 * My feeling is that planetariums are usually attached to a larger museum or observatory (which are mostly 'low' importance); a stand-alone planetarium is more limited so would be 'bottom'. But I suppose there could be similarly limited museums... I wonder if we're better off not being too prescriptive. <b style="font-family: Times New Roman; color: maroon;">Modest Genius</b> talk 11:42, 22 March 2024 (UTC)
 * I suppose it depends on how consistent we want the ratings to be. Without a baseline of comparison the ratings are more likely to be all over the map. Praemonitus (talk) 14:09, 22 March 2024 (UTC)
 * As mostly an outsider to this project, I would personally say that bothering with the distinction between "low" and "bottom" is a bit silly. I think using "bottom" to categorize topics only vaguely related to astronomy, like Mythology, is a clever use, tho. ~ Maplestrip/Mable ( chat ) 12:29, 22 March 2024 (UTC)
 * Low-rated articles are often still worth maintaining by this project. Bottom is for topics that are at best weakly related to hard-core astronomy, such as a sci-fi novel. Praemonitus (talk) 14:15, 22 March 2024 (UTC)

Sample
Here's a candidate Education block for the importance scale:


 * High: Major astronomy conferences, reputable astronomy training institutes, training principles.
 * Examples: Astronomy education, 'Department of Physics and Astronomy, University of Manchester', Lunar and Planetary Science Conference
 * Mid: College-level courses, special topic astronomy conferences, astronomy certifications.
 * Examples: European Association for Astronomy Education, Network for Astronomy School Education, National Standard Examination in Astronomy
 * Low: Public education and outreach, amateur astronomy associations, watch parties, astronomy museums, planetariums.
 * Examples: International Year of Astronomy, Faulkes Telescope Project, Hong Kong Astronomical Society, Sidewalk astronomy, Cosmos: A Spacetime Odyssey

Will this work? Praemonitus (talk) 14:05, 30 March 2024 (UTC)
 * As there was no objection, I added it to the importance scale. Now to go apply it. Praemonitus (talk) 14:47, 1 April 2024 (UTC)


 * There was no objection because you only waited 48 hours over the Easter holidays. I a) don't think we need a separate education section and b) feel you've been far too generous in rating these highly. There's no way that Manchester's university department is as important to the Wikiproject as red giant, Fritz Zwicky, SN 1987A or the other high-importance examples. Similarly, an obscure exam board in India is not 'mid' level. I think we should scrap this entire section - the old guidance was fine, just adding a couple of examples in the lower importances would have been adequate. <b style="font-family: Times New Roman; color: maroon;">Modest Genius</b> talk 15:12, 2 April 2024 (UTC)
 * Okay, I adjusted the ratings so they would be more in line with the Institution block. There is now only one entry in the High block. Does anybody else find the new ratings acceptable? I disagree with scrapping it, since I went looking for ratings guidance on astronomy education articles and found the previous list to be lacking. Better a more comprehensive list than leaving people guessing. Praemonitus (talk) 05:06, 5 April 2024 (UTC)

Superluminal astronomical objects
I am looking for a textbook or review to explain superluminal astronomical observations for Faster-than-light. AFAICT astronomers use the term "superluminal" as an observational category and thus the reviews of "superluminal sources" are matter of fact. The non-physical nature of "superluminal" does not even come up since (I assume) "everyone" knows that the term is empirical and no one things the speed of light limit is really exceeded. But I've not found a source that explains the issue. Suggestions? Johnjbarton (talk) 01:41, 11 April 2024 (UTC)


 * Just to give a concrete example: [ https://www.pnas.org/doi/abs/10.1073/pnas.92.25.11385 Superluminal sources.

Wikisky shut down? (Affecting several important infobox templates)
I have heard rumors that wiki-sky, a.k.a. Sky-Map.org, have shut down permanently. The page has long been used by a number of templates, used in thousands of astronomy articles on Wikipedia, in the form of links to a sky map (see Messier 94 and Alpha Centauri as examples; the link to the "coordinates" is at the top of the page). The page is currently offline, and has been for a few days. If this is indeed permanent, as I suspect, then we need a replacement, and some rather high-profile templates have to be edited quickly. Renerpho (talk) 15:17, 20 April 2024 (UTC)

Commons based WikiProject Astronomy?
Currently, there is no C:COM:WikiProject Astronomy, but there is alot of astronomical files and needs for categorization, file description, file name corrections, and perhaps building galleries. There are such wikiprojects on Commons, such as C:COM:WikiProject Aviation. The 2024 Great North American Eclipse talkpage has also been having debates on galleries lately, so building galleries on Commons can alleviate that  -- 65.92.247.66 (talk) 21:36, 24 April 2024 (UTC)

G299.2-2.9
So I just checked the “Did you know...” section on the front page of Wikipedia. And there is this interesting article: G299.2-2.9

The article says the object is 4,500 years old and 16,000 light years away from us. This doesn't make sense to me. Doesn't that mean its light has a speed of at least 3.6 times the speed of light? Nightwatcher773 (talk) 11:12, 29 April 2024 (UTC)
 * Well, it wouldn't've been 16,000 light years away from us 4,500 years ago, but I'm not sure if the expansion of the universe is that fast... ~ Maplestrip/Mable ( chat ) 11:17, 29 April 2024 (UTC)
 * I posted a guess at Teahouse that it's the age at which we see the supernova explosion, ignoring how long it took the light to reach us. PrimeHunter (talk) 11:19, 29 April 2024 (UTC)
 * I believe you are correct; the object is 16k ly away, but the nova reached us 4500 years ago. Primefac (talk) 11:37, 29 April 2024 (UTC)
 * I think I might say that we are observing it ~4,500 years after the event, so the reader can put it into context. Praemonitus (talk) 16:35, 29 April 2024 (UTC)
 * Convention in astronomy is to refer to transient events as occurring at the time they are seen on Earth; light travel time is not included. So for example SN 1987A happened in 1987 (when it was observed), not ~168,000 years ago (the time taken for light to travel that distance). There are good practical and theoretical reasons for this convention. <b style="font-family: Times New Roman; color: maroon;">Modest Genius</b> talk 16:07, 29 April 2024 (UTC)
 * The article says
 * "It is approximately 20,500 years old, and is older than most other Type Ia supernova remnants."
 * with two references. This sentence makes no sense to me. Surely there have been Ia supernovae for billions of years. Johnjbarton (talk) 17:40, 29 April 2024 (UTC)
 * The 4500y date is correct according to the ref. This value is computed from the observed radius and a relation due to Sedov, see
 * Xu, Jian-Wen, Xi-Zhen Zhang, and Jin-Lin Han. "Statistics of galactic supernova remnants." Chinese Journal of Astronomy and Astrophysics 5.2 (2005): 165.
 * I applied the correction to the article. Johnjbarton (talk) 17:51, 29 April 2024 (UTC)


 * I suspect what they are saying is that SNRs don't last very long before dispersing into the surroundings. Praemonitus (talk) 19:03, 29 April 2024 (UTC)

Duplicated lists for Mars missions
There is this List of missions to Mars, and there are three lists that are mostly duplicates, List of Mars landers, List of Mars orbiters, and List of artificial objects on Mars. I think both can be safely redirected to the main list without any loss of content, with a little merge from the third article (section on garbage on Mars). What do you all think? Artem.G (talk) 12:43, 15 April 2024 (UTC)
 * It looks like the List of Mars landers has information columns that the List of missions to Mars does not, so there would be a loss of content on a redirect. Praemonitus (talk) 14:00, 15 April 2024 (UTC)
 * hmm, ok, valid point. But list of landers and list of artificial objects are almost the same, the only major difference is that failed missions are listed in the first list and obviously not liated in the second. Artem.G (talk) 15:19, 15 April 2024 (UTC)
 * I'd say any material unique to the subsidiary lists should be merged to List of missions to Mars; there's really not much point in having separate lists for landers, orbiters, and "artificial objects" ArkHyena (talk) 19:32, 18 April 2024 (UTC)
 * I do think having separate lists for landers and orbiters, alongside the general list of all missions, is reasonable. I think the "objects" list should be merged into the other two lists. The fact that orbiters have and will impact Mars is vaguely interesting for the orbiter list; memorials placed by landers is vaguely interesting for the landers list; but for the most part it's just a copy of everything else. ~ Maplestrip/Mable ( chat ) 07:44, 1 May 2024 (UTC)

Creating a new template
We currently have templates for citing catalogs, such as exoplanet.eu Cite EPE, Gaia DR2 Cite Gaia DR2, SIMBAD Cite simbad, among others. However, I miss a template to cite the NASA Exoplanet Archive, which is also a large catalog of exoplanets. The template name could be Cite NEC or Cite Exoplanet Archive and the style could be like this:

HIP 39017 Overview. NASA Exoplanet Archive. Acessed on 2024-04-30.

I don't know how to make templates, so anyone experienced could make this. InTheAstronomy32 (talk) 12:47, 30 April 2024 (UTC) Template links fixed, no content change. Primefac (talk) 12:50, 30 April 2024 (UTC)
 * Speaking to the technical aspect of it, you'd probably want something like:
 * So if you input you would get out
 * A quick search shows ~280 pages calling the exoplanet archive, so it's not unreasonable to have a template for the job. I'll wait for more feedback before creating it, though. Primefac (talk) 13:00, 30 April 2024 (UTC)
 * Ok, thanks. InTheAstronomy32 (talk) 13:04, 30 April 2024 (UTC)

Nomination of 2MASX J22550681+0058396 (and many other stubs by User:Galaxybeing) for deletion
A discussion is taking place as to whether the article 2MASX J22550681+0058396 is suitable for inclusion in Wikipedia according to Wikipedia's policies and guidelines or whether it should be deleted.

The article will be discussed at Articles for deletion/2MASX J22550681+0058396 until a consensus is reached, and anyone, including you, is welcome to contribute to the discussion. The nomination will explain the policies and guidelines which are of concern. The discussion focuses on high-quality evidence and our policies and guidelines.

Users may edit the article during the discussion, including to improve the article to address concerns raised in the discussion. However, do not remove the article-for-deletion notice from the top of the article until the discussion has finished. Parejkoj (talk) 17:39, 8 May 2024 (UTC)

I've also nominated many other articles created by User_talk:Galaxybeing, and there are more yet to delete. If someone has a more automated way to go through these, that would be great: I've been adding them to the deletion list one at a time, and that's getting tedious. It may be more worthwhile to see if any of these new articles are notable enough to keep and just delete them all otherwise. We'll see if the author responds. - Parejkoj (talk) 17:41, 8 May 2024 (UTC)
 * What I typically do in such cases is search for papers on the object, and if those are lacking I slap on a notability template and let it cook for a while. Praemonitus (talk) 04:14, 9 May 2024 (UTC)
 * The problem is this user has created dozens (over a hundred by my estimate) of pages like this. They're almost all stubs with generic information pulled from catalogs and non-reliable sources (e.g. Go-astronomy, In-the-sky, and cseligman). I'd rather propose a "delete all of these pages and require the submitter to propose them for creation based on notability", but I'm not sure that there's a process for that. - Parejkoj (talk) 17:23, 9 May 2024 (UTC)
 * Understood, and I'm highly aware as I've been checking their WikiProject ratings. But I do have civility concerns about mass censoring an editor in that manner. Perhaps if there were a list of IC objects (since it's an extension of NGC) and we redirected the non-notable articles there? At least some of those articles do appear notable; I'd particularly check the ones with Hubble images, or more detailed information. Finally, the cseligman source at least seems pretty reliable. Praemonitus (talk) 18:08, 9 May 2024 (UTC)
 * Fair point on the civility concerns: I get a bit punchy when someone mass-creates a bunch of pages for random objects from catalog papers, since there are so many catalogs to pull from and so many junk webpages that just mindlessly compile those catalogs for pageviews. That said, just having Hubble images doesn't make something notable either: there are millions of HST images of objects, and unless it was a dedicated campaign for that ended in a paper for that object, it doesn't make it notable; the astronomical object notability guidelines are pretty clear. - Parejkoj (talk) 23:15, 9 May 2024 (UTC)
 * Right, but my experience has been that a publically-published Hubble image of an object usually means an associated article, which means potentially substantial content per WP:GNG. To me it's a tell, and at least deserves more investigation. Praemonitus (talk)

 * Being a deceased member of the IAU doesn't make someone notable. Anyone with a PhD in astronomy or related fields can join, a few years ago they opened membership to students studying for one. It's not some elite fellowship or award. (FWIW, I am an IAU member and don't pass WP:NPROF.) Some of the people on that list will turn out to be notable for other reasons, but I expect the vast majority are not. <b style="font-family: Times New Roman; color: maroon;">Modest Genius</b> talk 10:40, 10 May 2024 (UTC)
