Yes, please For example, it would be useful when writing things involving c, astronomy equations, and the like. Also, it's not that terribly hard on load times.

To emphasize the intimate link between astronomy and mathematics, I'll post a scan of a cheat sheet for Astronomy 150 from Andy's useful astronomy/physics/math cheat sheets page, a (formerly) junior-level astronomy college course at Harvard on radiative processes in astrophysics: This is one of four cheat sheets for this class, this being the first and ...

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.

Questions which would benefit from a mathjaxy answer (Updated 10/14 - Feel free to add more.) How do I calculate the inclination of an object with an amateur telescope? How to calculate the movement of the object passing near other object in space? What is a parsec and how is it measured? How is it known that Callisto has no core? What is the formula to ...

List of examples: Determining effect of small variable force on planetary perihelion precession (formula looks awful right now) Another example where it would be useful; the OP explicitely asked for a formula (and my answer is poorly typesetted with no math typesetting support) How much oxygen did the Warwick/Cambridge study find in the rocky debris around ...

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'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"

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 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.

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 ...

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

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: ...

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.

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.

It's perfectly reasonable to have both, in my opinion. They aren't really the same thing. Orbit might be considered of course as a type of trajectory (i.e. orbital trajectory), but what's usually implied with the latter is non-orbital trajectories, such as parabolic-, hyperbolic-, ballistic-,... So yeah, I say we keep them both, see if they later need ...

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 ...

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.

Nice Job putting together this proposal. This has been… $$\Huge DONE$$

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 ...
