翻譯: 觀測和記錄天文現象的活動。
學術領域
EN: The academic discipline or body of knowledge concerning the universe beyond Earth's atmosphere.

astronomy vs astrology
「astronomy」是研究天體和宇宙現象的科學；「astrology」則是占星術，一種認為天體位置會影響人事的信仰體系。
astronomy vs cosmology
「astronomy」主要關注觀測和描述個別天體與現象；「cosmology」則是宇宙學，研究宇宙的整體起源、結構和演化。
astronomy vs astrophysics
「astronomy」是更廣泛的天文學，包含觀測、分類和測量；「astrophysics」是天體物理學，專注於應用物理學原理來理解天體的性質和行為。
在對話中，當引述或提及他人對天文學的看法或事實時，常會用「astronomy」來開啟話題。 EN: My daughter told me she wants to study astronomy in college. 翻譯: 我女兒告訴我她想在大學裡攻讀天文學。
EN:He was saying how amateur astronomy has gotten so much easier with new apps.
翻譯:他說現在有了新應用程式，業餘天文學變得容易多了。
在口語中，有時會用「astronomy」來強調某件事的規模、複雜性或令人驚嘆的程度，帶有比喻色彩。 EN: The cost of that project isn't just high, it's astronomical! 翻譯: 那個專案的成本不只是高，簡直是天文數字！
EN:Figuring out their relationship dynamics requires a degree in social astronomy.
翻譯:要搞懂他們之間的關係動態，簡直需要一個社會天文學的學位。
在組織思緒或尋找合適詞語時，說話者可能會用「astronomy」或相關短語作為短暫的停頓填充，尤其是在談論科學、教育或宏大主題時。 EN: His main interests are, you know, astronomy, physics, that sort of thing. 翻譯: 他的主要興趣是，你知道的，天文學、物理學，那一類的東西。
EN:We were talking about the universe and... astronomy... and how little we actually know.
翻譯:我們當時在討論宇宙和...天文學...以及我們實際上所知甚少。
正式寫作注意：在學術論文、正式報告或技術文件中，應避免將「astronomy」用於非字面意義的比喻或作為填充詞。請嚴格使用其專業學科定義，並確保上下文精確嚴謹。

Astronomy is an uncountable noun (like physics or biology). You cannot pluralize it. Use "astronomy books," "astronomy articles," or "works on astronomy" instead.
×He is professor of astronomy.
✓He is a professor of astronomy.
When referring to a person's profession or role, the indefinite article "a" is usually required before the singular noun.
×He majored on astronomy at university.
✓He majored in astronomy at university.
The correct preposition to use with "major" (as a verb) when referring to an academic field is "in."
×I love Astronomy and Physics.
✓I love astronomy and physics.
Academic subjects are not capitalized unless they are part of a proper noun (e.g., "Department of Astronomy") or are languages (e.g., English).
