To the best of my understanding, the kind of vague, high-level "meta" tag that science represents is generally discouraged. I agree - kill it with malice.

This UC Berkeley page seems to peg the CMB as the end of the early universe period. We should give a little bit for some of our astrophysics professionals around here to weigh in, but otherwise I think that's what we should go with.

I suspect tbinary was a typo for ebinary, and I think they are referring to eclipsing binaries. I think both tags should be replaced with eclipsing-star-systems.

Update: There's a catch to being able to do this right away. See discussion in the comments. These definitely should be merged. The only reason I could see for having a distinction would be for distinguishing between [Earth] atmospheric effects on observation and the study of atmospheres on other planets. That said, atmosphere is currently being used for ...

I've recreated the tag but if you want to keep it around for more than six months, find another question to add it to or give it a tag wiki. Or, if you decide that you don't want it, just remove it from the question and it will go away in 24 hours. This hinges on a prohibition in tag creation coupled with a synonym where the master is deleted. Long ago we ...

Yes, and the singular form should have precedence, compare with other popular tags such as "star" or "black-hole"

My top two favorite resources for the scope of any Stack Exchange site are, in order, the tour and the help center. The former takes maybe a minute or two to read and should clear up some basic questions; the latter is useful for more specific concerns about scope and allows us to be more explicit about certain unique rules and guidelines. The help center is ...

The site switcher currently shows the current site in the first position and your top few sites (by your reputation) "above the fold". The rest of the sites are located under the "Find a Stack Exchange site" search bar. So even though I have an account on every single site my site switcher looks like this: It more or less matches what I see in my flair: ...

That was an accident. I apologize for the mistake. I have undeleted your answer.

Several sites (The First Stars and Galaxies, for example) place the formation of the first stars as happening in the early universe period. This happened well after the CMB. NASA pegs the early universe as ending even later with the formation of the first galaxies. This is in line with the two questions raised in this meta question.

I was the OP of the question that uhoh mentioned in the question and I just used the "resource" tag to search for questions similar to mine. The presence of two similar tags of the same meaning is just misleading and may cause the creation of more duplicate and redundant questions. So, unless the two tags do have different meanings, is it possible ...

The time tag currently has 17 questions, and date-time currently has 58. Neither of them have a tag wiki. They seem to be used for exactly the same purpose. I think we should 1) make date-time a synonym of time, 2) add a tag wiki for time, 3) retag questions that don't follow the new tag wiki.

the-sun and the-moon are now the official tags. lunar is now a synonym of the-moon. moons is now a synonym of natural-satellite. Only developers can blacklist tags, but I don't think we need to blacklist moon. I made it a synonym of the-moon. Even though moon is ambiguous, in most cases people will be looking for the-moon. When they are not, they will see ...

I think sky-survey is totally fine. Among astronomers, these are normally just called "surveys" because the "sky" part is implied by context and the background of the people having the discussion. For the more general audience of SE, putting the "sky-" prefix before it helps remove any ambiguity about what is being surveyed (and would be in good company of ...

All of them have a substantial number of questions, but you are right that spectrum should be consolidated under spectra. Otherwise, I think we should probably leave them be, but spectrometry needs a tag excerpt.

UPDATE: It has now been enabled on the site. I'm going to hazard a guess that since this has a net score of 10 currently, which is an ample amount for Astronomy meta, the community is generally interested in this. I could see it being useful in some cases as a visual aid for things that can be kind of hard to envision from a textual description, especially ...

This is a simple enough request, so I've gone ahead and performed the merge; I can't think of a reason not to. In the process, I also created a synonym mapping hst to hubble-telescope. If we see something like hubble-space-telescope arise, I can merge that, if need be. But for now it looks like we're all good.

The tag foundamental-astronomy has been marked as a synonym of fundamental-astronomy. Users can't actually use "foundamental astronomy" - everything automatically routes, corrects, and or renames to fundamental-astronomy.

I've never really liked questions about lights in the sky. They tend to list the location, time, and color of the lights . . . and that's about it. Invariably, we have nowhere near enough information to give an accurate answer because none of us were there at the same time, and we have no way to gather additional data. It's so bad that we tend to close them ...

I don't think we need both tags. I suggest merging the chemistry questions into astrochemistry, as we have astrobiology but no biology tag. I don't think we should create a synonym between chemistry and astrochemistry though. chemistry only has four uses this year, so I don't think it will be a big deal to retag manually in the future. That said, we should ...

The only difference seems to be that observation discusses a singular object, and observational-astronomy discusses multiple. Looks to me that these tags could be merged since basically observational-astronomy encompasses observation and questions could be altered to define if the question is about a singular object or multiple.

These seem to be the questions tagged measurement that are about some kind of measuring. I think that for all except "measure the age of the universe" the observational-astronomy tag would be fine. I've no objection to the proposed synonymization. How do we measure the age of the universe? How do we measure the brightness of the stars? What ...

Yeah, this seems like a junk tag. My inclination would be to retag the questions with more specific tags. When there are no laws-of-physics questions left, the tag will be automatically deleted.

I agree that tidal-forces concept is the driving force (literally) for ocean tides. Bodies have solid-tides as well, so we should either have three tags or one. I kind-of like the idea of having all three tags, but then what should we call the tides that the moons of gas giant planets induce in the gas? Or the tides produced in a star by a large companion (a ...

My understanding is that atmosphere and planetary-atmosphere tags will be merged and called planetary-atmosphere, so I will treat them as one in my summary below. I've set about the following scripted task: For all questions with the atmosphere or planetary-atmosphere tags that are not about planetary atmospheres remove those tags. Then if they need ...

Based on a quick Google search, they do appear to be completely synonymous. I think we should prefer habitable-zone as the main tag and make goldilocks-zone a synonym, because "habitable" is a more plain rendering of the concept whereas "goldilocks" requires an understanding of the British fairy tale and how the parallel is drawn ("...

As I noted over yonder, this has been fixed now. Thanks for the report, and please join me in thanking rene for digging up the archived page!

I'll merge them. As for your last question, we could make a sagittarius-a-asterisk tag, but since Sagittarius A* is a component of Sagittarius A, I don't see the need for a separate tag.
