Recent scientific breakthroughs have transformed our understanding of the Moon, moving beyond simple theories to solid, evidence-based insights.
近期的科學突破改變了我們對月球的認知，從單純的理論演進至堅實且有證據支撐的洞見。
For decades, the lunar mantle remained a mystery because early missions only retrieved crustal samples.
數十年來，月球地函一直是個謎，因為早期任務僅帶回了地殼樣本。
A landmark discovery highlights a significant hemispheric dichotomy: the Moon’s farside mantle is much drier than the nearside mantle.
一項具標誌性的發現凸顯了顯著的半球二分性：月球背面地函比正面地函乾燥得多。
This asymmetry suggests that the Moon’s interior is not a uniform sphere but is highly heterogeneous.
這種不對稱性表明，月球內部並非均勻的球體，而是具有極高的異質性。
Research also confirms a 'mantle overturn' process, where dense materials sank while lighter ones rose, explaining the presence of iron-rich elements in volcanic regions.
研究也證實了「地函翻轉」過程，亦即密度較大的物質下沉，而較輕的物質上升，這解釋了火山區富含鐵元素的原因。
Furthermore, gravity-based models indicate that the massive South Pole-Aitken impact likely excavated deep mantle material, potentially bringing it within reach for future explorers like the Artemis missions.
此外，基於重力的模型顯示，龐大的南極艾特肯盆地撞擊很可能挖掘出了深層地函物質，並有望讓未來像阿提密斯任務的探索者們能夠觸及。
By analyzing these compositions, scientists are refining our knowledge of the 'giant-impact hypothesis' and the Moon's cooling history.
透過分析這些成分，科學家們正在完善我們對「巨型撞擊假說」及月球冷卻史的認知。
Far from being a static rock, the Moon is revealed as a geologically dynamic world with an Earth-like internal structure, including a solid inner core and a partially molten core-mantle boundary.
月球絕非靜態岩石，而是一個地質活躍的世界，並且具有類地球的內部結構，包含固態內核與部分熔融的核函邊界。
