I've asked a question on why some graph absorption pattern is shown on Earth. Based on information that Venus did not show this pattern. However, I could at the time not find a source that shows Venus does not show this pattern, so I thought it would be best to focus the question on asking why Earth shows this pattern (as I expected I would be able to derive the reason for that difference from that answer).
This question has been answered, and the answer, does not answer why it is shown on Earth but not on Venus, nor am I able to derive that from the answer. By now I have found the evidence that the pattern is not shown for Venus and included it in the question.
However, I am in doubt, whether it is better to change the question (back) to: "why is the pattern shown on Earth and not on Venus?" or whether it is better to keep the question on: "Why does Earth show this pattern?" and ask a new question with: "why is the pattern shown on Earth and not on Venus?"
For completeness this is the question my doubt is about.
As pointed out by Connor Garcia♦, unchanged I think the question is not a best fit for Astronomy as it then is about Earth sciences. At the time of writing I did not realize this due to the XY-problem which is related to Astronomy. So if it is best to keep the question unchanged and ask a new question, I think I will vote to move the question to the Earth sciences site.
