Fixed a broken link, added Swift and Swift XRT link Rob 05:19, 12 March 2006 (UTC)
When I clicked on the link about HIREGS ( http://sprg.ssl.berkeley.edu/balloon/) it was broken. I navigated to the front page of the website and found the link to it and it was gone. Therefore I have made the link link to an archived version of a page. It can be found here. Hope I helped! —The preceding unsigned comment was added by The Psychless ( talk • contribs) 22:39, 25 April 2007 (UTC).
"x-ray telescope" redirects here but there was no information on the design of x-ray telescopes to show what angular resolution or imaging capabilities they have or can have. I've linked to a few docs until someone can do a proper job. Rod57 ( talk) 00:06, 10 September 2008 (UTC)
A great deal of useful information has been added in the past day or two by Marshallsumter ( talk), for which I am very grateful and pleased. Some of it raises questions in my mind, however, about organization—the enumeration of missions, experiments, and instruments, versus exposition of astronomy issues. I have tried to add some information about missions I have been particularly familiar with, such as OSO 7, HEAO 1 (A4), HEAO 3 (C1), and CGRO. The articles on the Orbiting Solar Observatory series is particularly sparse, as each one deserves its own short article, plus an article about the overall NASA OSO program. The articles I have worked on are unbalanced in that instruments and spacecraft I know little about are woefully shortchanged. Some of the new material here by Marshallsumter could be used to start stubs for the other OSO's and fill in instrumental detail. Another issue is that the key science results of individual instruments have been shortchanged in the mission and instrument discussions, and it seems to me that that kind of material ought to find a place here, as well as be mentioned under the hardware, missions, and techniques articles. I guess I think the amount of material potentially involved is so large that many editors must necessarily be involved, adding material they know about (and can reference, I hope, of course) and then when enough material has been collected to approach something comprehensive, we are likely to want to undertake a really large-scale re-organization of the whole subject, into articles covering missions, articles on specific objects (eg, the Crab Nebula and Cygnus X-1), articles on experiments and instruments, articles on instrumental techiques, and finally and article trying to tie what all these different strands have taught us about astronomy and the universe, the sort of thing and senior college student thinking of specializing in the subject might find useful. This will take a while I think! But a worthy goal nonetheless, and something only Wikipedia can possibly attempt. Wwheaton ( talk) 04:05, 20 September 2009 (UTC)
I agree with pretty much every subject Wwheaton has touched on. I have the same goals. My next contribution probably will deal with the various catalogs of X-ray objects and possibly the individual contributions by each effort though that will be Herculean to accomplish right away. I also agree regarding making this subject attractive enough that advanced undergrads will think about a career in X-ray astronomy or related area. I have no objections to parsing out info to various connected articles. Marshallsumter ( talk) 02:08, 21 September 2009 (UTC)
I've been thinking about re-organizing the material for this article into more of a newspaper style as follows:
While I have reasons for each in this order, I'd like some feedback before actually re-arranging everything. Marshallsumter ( talk) 16:19, 4 October 2009 (UTC)
I tend to agree. I've already prepared a section on "X-ray generation" but haven't included it precisely because of article length considerations. To handle this in a limited way, I've been expanding some shorter stubs and articles such as Super soft X-ray source and creating articles such as Stellar surface fusion. I'd also really like to have an article dedicated to "X-ray telescopes", including the optics for both glancing angle and the multilayer films used in direct incidence. Detectors might also deserve their own smaller article. Ironically, when I was looking at the Feature Articles produced in Astronomy, I found that no science article (e.g. Astronomy) has ever been a Feature Article. This is disconcerting. Is it that a science article never has the appropriate pizzazz? Or that wonderment is only attached to the startling and unexpected. Marshallsumter ( talk) 08:00, 18 October 2009 (UTC)
We've gone back and forth on how to link this. The term "modulation collimator" has a significance far beyond its constituents, which I think should be linked in a proper article on the subject. There is a rich history here, starting with the identification of Sco X-1 (which, incidentally, was neither at the Galactic Center nor very closely related to what Giacconi got the Nobel Prize for, as earlier versions suggested). It seems that people who understand RMCs, URAs, and the like, are not paying enough attention to the Wikipedia!
This article is (a) too big, and (b) too undiscriminating in its overview. I haven't had time to go through it in detail but noticed many things that need to get improved. One of these things near the top was "modulation collimator" so I suggest that Marshallsumter accept my improvement there. Another thing I noticed was NiXT - if one is going to mention that, one needs to mention Art Walker's work, which basically came first.
-- Hugh Hudson ( talk) 21:34, 24 October 2009 (UTC)
It has been pointed out that this article has become exceedingly long; much longer than is recommended by WP:LENGTH. To quote that page, "Readers may tire of reading a page much longer than about 30 to 50 KB, which roughly corresponds to 6,000 to 10,000 words of readable prose." I suggest splitting out the longer (and sufficiently notable) sections of this article into sub-articles, while still describing them here using WP:SS. Thank you for your consideration.— RJH ( talk) 18:24, 15 November 2009 (UTC)
I have split off several articles from this one already: Stellar X-ray astronomy, Solar X-ray astronomy, X-ray telescope, Stellar surface fusion, X-1 X-ray Source, Sounding rocket X-ray astronomy, X-rays from Eridanus and have added material to Super soft X-ray source, e.g. I like the idea of an article Astronomical X-ray source since we have so many different types. And, agree with making each major section its own as well. If there are no major objections, I'll go ahead and split off a few more sections and see what happens. Marshallsumter ( talk) 07:41, 16 November 2009 (UTC)
I just performed an edit to see the article size. It's still big at 106 kb, even after spawning 10 split-offs! Yikes! Although 106 kb is the same size as the Sun Feature Article - which itself has a suggestion on its discussion page to have it split up. Marshallsumter ( talk) 19:47, 17 November 2009 (UTC)
From looking through the list of Wikipedia Feature Articles, I was struck by two facts: (1) the only article about a science to be a FA is Cryptography and (2) Warfare has more FAs than any other area. Splitting off some more sections and including let's say the best from each section in X-ray astronomy with a flowing connectivity of prose will help readability but I've always been fuzzy on the "quality" thing once good grammar has been achieved and readability reached. So, unless there are some major objections I believe we have improved the article quite a bit and of course there's always room for more, I'm going to remove the Cleanup box. Marshallsumter ( talk) 20:03, 17 November 2009 (UTC)
The Featurette section is not typical of Wikipedia articles, but this and other X-ray astronomy articles have them. Rather, they appear to be more like what is found on Portals. I suggest that these sections be transferred to a Portal:X-ray astronomy
76.66.197.2 ( talk) 06:01, 19 November 2009 (UTC)
Wikipedia has a nice description of Featurette and its various meanings over time. What I had in mind with the experiment was a featurette that show-cased a most recent event in the particular subject, such as GOES 14 launched this year with an X-ray imaging telescope on board to observe the Sun. It's the most recent satellite launched with an aspect of X-ray astronomy in mind yet in its case with a practical need. I like the newer one as well. It showcases some new with some neat items and some unusual ones from the history of X-ray astronomy. It's a bonus that lets the reader know the content of the article is fairly up-to-date and subject-encompassing. I believe it should have good images, short but relevant text and at least some recentness. Comments, questions, criticisms are most welcome? Marshallsumter ( talk) 22:44, 20 November 2009 (UTC)
Featurettes highlighting something happening in a topic is more like what is found in a book, rather than in an encyclopedia entry, and DYK, and current happenings are what portals are for. The Main Page is a portal. 76.66.197.2 ( talk) 05:53, 21 November 2009 (UTC)
I think the organization of the material regarding individual sources needs more thought. We now have an article entitled " X-rays from Eridanus", and another " X-1 X-ray source", which seem like poor choices to me. I object to articles with these scopes (sources in Eridanus, sources whose names begin with "X-1") because (in my opinion) constellations and outmoded designations are not sufficiently astrophysically notable to serve as organizing principles. I would much prefer a big table of X-ray sources, with some minimal information in the columns of the table: say, name or identification, position, few-character type code, peak or average intensity, discovery date, constellation if you like, and a wikilink in the first column to a dedicated article if one exists (meaning there is enough reliable information to support one), etc. Right now such a table would have a few thousand entries, and a fair fraction of the sources could have their own articles. We should realize that as instruments (and sky coverage) improve, the number of known sources is destined to explode. This is happening now for asteroids, and happened long ago for stars. Do we really want to start articles that are inevitably doomed (for the Eridanus case) to eventually have 3,000 unrelated sections for a heterogeneous collection of objects, many of which also merit separate, redundant, articles? I have similar feelings about the "X-1" source article, only even more so (why not X-2? and X-3?....)
A similar issue has come up for asteroids, where I hope we will have consensus soon. The asteroidal situation is simpler because we organize it by discovery number, as assigned by the Minor Planet Center, and those numbers are permanent so each object stays put in the table. For X-ray sources the organization in the table is more complex, and it seems like the best we can do is source position (J2000 will have to serve for the next 20 years I guess) by RA and Dec, and even that does not give a unique numerical rank & position in the table as new, fainter sources are discovered. Also, numbered asteroids are "forever" (like Love & herpes...), and therefor inherently notable, but X-ray sources are often transient and (only a few nowadays) sometimes mistaken altogether, so each entry in the table will have to have at least one link to a reference establishing its authority as notable. (A possible alternative would be the system the astronomical community has long used for stars and other fixed objects, of having many separate catalogs produced by different projects. For Wikipedia a table of external source catalogs might be a way to go.)
Anyhow, this brings up a whole can of worms needing more discussion with more voices and more brains. The actual contents of the table I think should be a separate issue from the principal of having such a master table, linking to separate source articles as appropriate. After others have time to weigh in, I envisage a formal proposal for such a scheme, and if that is accepted, would then open a new discussion on the details of the organization of the table itself. Wwheaton ( talk) 19:06, 20 November 2009 (UTC)
This is a tough one! May I suggest checking out the History of astronomy for guidelines. Or, as I prefer the History of visual astronomy. We are facing a similar problem with X-ray astronomy. I've put some comments on the discussion pages for X-rays from Eridanus and X-1 X-ray source that may help. What I had in mind was multiple locations that individual objects can be presented even if they do not as yet have at least a stub, or the article, like Epsilon Eridani, may be getting too long - yet doesn't even mention X-rays. Duplication should be kept to a minimum - my apologies on that. As the X-ray spectrum covers 6x the visual at least and it is very likely almost every visual source will also be an X-ray source but not every X-ray source will have a visual counterpart, the ultimate number of X-ray sources could be 6x the visuals for our galaxy alone. There are some additional concerns. Most of our astrophysics, astrochemistry and the like have there basis in visual astronomy. As X-ray and gamma-ray astronomy expand, we may find the universe is far stranger than we thought which means that we need flexibility in article topics and style. Well, I guess I've tossed in enough confusion for now - but I hope these comments help. Marshallsumter ( talk) 23:24, 20 November 2009 (UTC)
I have created an Index table for X-ray and gamma-ray sources based on this discussion and suggestions made by Wwheaton ( talk). Have a look and feel free to comment, criticize, etc. Marshallsumter ( talk) 02:21, 16 March 2010 (UTC)
I did the splitting and merging to help organize the material. If Marshallsumter or some other editor wants to add some of that material back into the main article there is nothing to prevent it. As Marshallsumter pointed out the "Sun" article is 100K and I noticed that "Electron" is 100k. Both of these articles have achieved FA status, so I guess 100K is no major shortcoming. When adding some of the material back in the main article I reccomend following the merge Guidelines at the Help: merge page. I find the Quick reference section the most effective for me at Help:Merge#Quick_reference. Also, in this case I don't see a need for a merger proposal beforehand, imho. Steve Quinn (formerly Ti-30X) ( talk) 04:35, 21 November 2009 (UTC
I've created the article Balloons for X-ray astronomy initially expecting it to be a stub. However, the subject even on Wikipedia is larger than I thought. The sections here that regard balloons have been included. I was wondering if we want to delete any of the balloon portions of this article or keep them. Marshallsumter ( talk) 18:54, 2 December 2009 (UTC)
I have looked at some of the portals currently available and have some questions which I hope someone can answer. When I type in a topic Wikipedia usually takes me to that main page, would it take me to the portal or the main page for "X-ray astronomy" or do I have to specify "Portal: X-ray astronomy"? While most of my inquiries are scientific, a few are social or cultural, and I've never been taken to any portal, so how many of them are there per main page? And do readers really know how to get to them, and do they help and increase readership for that subject? The confusion issue mentioned under "Featurette"s could be handled with quick links and better writing but if the above questions can be answered, it's okay with me to have a Portal: X-ray astronomy and use the Featurette material in this way, for example. Marshallsumter ( talk) 20:51, 15 December 2009 (UTC)
In the first sentence it states that there are shock waves going out from the star at supersonic speeds. This needs to be clarified and/or corrected because sound cannot travel through a vacuum, hence everything moving is at supersonic speeds in space. —Preceding unsigned comment added by 70.252.81.84 ( talk) 16:50, 18 August 2010 (UTC)

Hello out there! I ended up on this page thanks to my work on Solrad. There's a lot of great info on this page, but it's once again gotten a bit unwieldy. Moreover, the heading I encountered wasn't very accessible, not discussing the *why* we thought X-ray sources might exist and went looking for them. Finally, the Giacconi digression in the second paragraph seemed misplaced.
I've (hopefully) patched up the beginning a bit, and I moved the Giacconi verbiage to the Sounding Rockets section, the only other place he is mentioned, along with adding some reference links to cover bases.
The article could really use a run through with a nice opening few paragraphs on the science of it and then maybe just a notable flights list and a link to a more comprehensive page? I don't know. I'm new here and in over my head. :)
Anyway, I hope you like what I've done with the page. Thank you! -- Neopeius ( talk) 01:38, 5 January 2019 (UTC)

Also, numbered asteroids are "forever" (like Love & herpes...), and therefor inherently notable, but X-ray sources are often transient and (only a few nowadays) sometimes mistaken altogether, so each entry in the table will have to have at least one link to a reference establishing its authority as notable. (A possible alternative would be the system the astronomical community has long used for stars and other fixed objects, of having many separate catalogs produced by different projects. For Wikipedia a table of external source catalogs might be a way to go.)
Anyhow, this brings up a whole can of worms needing more discussion with more voices and more brains. The actual contents of the table I think should be a separate issue from the principal of having such a master table, linking to separate source articles as appropriate. After others have time to weigh in, I envisage a formal proposal for such a scheme, and if that is accepted, would then open a new discussion on the details of the organization of the table itself.

This is a tough one! May I suggest checking out the History of astronomy for guidelines. Or, as I prefer the History of visual astronomy. We are facing a similar problem with X-ray astronomy. I've put some comments on the discussion pages for X-rays from Eridanus and X-1 X-ray source that may help. What I had in mind was multiple locations that individual objects can be presented even if they do not as yet have at least a stub, or the article, like Epsilon Eridani, may be getting too long - yet doesn't even mention X-rays. Duplication should be kept to a minimum - my apologies on that. As the X-ray spectrum covers 6x the visual at least and it is very likely almost every visual source will also be an X-ray source but not every X-ray source will have a visual counterpart, the ultimate number of X-ray sources could be 6x the visuals for our galaxy alone. There are some additional concerns. Most of our astrophysics, astrochemistry and the like have there basis in visual astronomy. As X-ray and gamma-ray astronomy expand, we may find the universe is far stranger than we thought which means that we need flexibility in article topics and style. Well, I guess I've tossed in enough confusion for now - but I hope these comments help. Marshallsumter ( talk) 23:24, 20 November 2009 (UTC)
I have created an Index table for X-ray and gamma-ray sources based on this discussion and suggestions made by Wwheaton ( talk). Have a look and feel free to comment, criticize, etc. Marshallsumter ( talk) 02:21, 16 March 2010 (UTC)
I did the splitting and merging to help organize the material. If Marshallsumter or some other editor wants to add some of that material back into the main article there is nothing to prevent it. As Marshallsumter pointed out the "Sun" article is 100K and I noticed that "Electron" is 100k. Both of these articles have achieved FA status, so I guess 100K is no major shortcoming. When adding some of the material back in the main article I reccomend following the merge Guidelines at the Help: merge page. I find the Quick reference section the most effective for me at Help:Merge#Quick_reference. Also, in this case I don't see a need for a merger proposal beforehand, imho.

I've created the article Balloons for X-ray astronomy initially expecting it to be a stub. However, the subject even on Wikipedia is larger than I thought. The sections here that regard balloons have been included. I was wondering if we want to delete any of the balloon portions of this article or keep them.

I have looked at some of the portals currently available and have some questions which I hope someone can answer. When I type in a topic Wikipedia usually takes me to that main page, would it take me to the portal or the main page for "X-ray astronomy" or do I have to specify "Portal: X-ray astronomy"? While most of my inquiries are scientific, a few are social or cultural, and I've never been taken to any portal, so how many of them are there per main page? And do readers really know how to get to them, and do they help and increase readership for that subject? The confusion issue mentioned under "Featurette"s could be handled with quick links and better writing but if the above questions can be answered, it's okay with me to have a Portal: X-ray astronomy and use the Featurette material in this way, for example.

In the first sentence it states that there are shock waves going out from the star at supersonic speeds. This needs to be clarified and/or corrected because sound cannot travel through a vacuum, hence everything moving is at supersonic speeds in space. —Preceding unsigned comment added by 70.252.81.84 ( talk) 16:50, 18 August 2010 (UTC)
In a merge discussion for Neupert effect to the X-ray page it has been proposed to merge Neupert Effect to the X-ray astronomy page... Editors of this page are invited to comment there ( Talk:X-ray#Neupert_effect_merge_discussion) please... Gremlin SA 09:31, 23 February 2015 (UTC)

Hello out there! I ended up on this page thanks to my work on Solrad. There's a lot of great info on this page, but it's once again gotten a bit unwieldy. Moreover, the heading I encountered wasn't very accessible, not discussing the *why* we thought X-ray sources might exist and went looking for them. Finally, the Giacconi digression in the second paragraph seemed misplaced.
I've (hopefully) patched up the beginning a bit, and I moved the Giacconi verbiage to the Sounding Rockets section, the only other place he is mentioned, along with adding some reference links to cover bases.
The article could really use a run through with a nice opening few paragraphs on the science of it and then maybe just a notable flights list and a link to a more comprehensive page? I don't know. I'm new here and in over my head. :)
Anyway, I hope you like what I've done with the page. Thank you! -- Neopeius ( talk) 01:38, 5 January 2019 (UTC)
