New discoveries about the Moon's mantle revealed

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。
Recent scientific breakthroughs have transformed our understanding of the Moon, moving beyond simple theories to solid, evidence-based insights.
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。
For decades, the lunar mantle remained a mystery because early missions only retrieved crustal samples.
然而，來自像嫦娥六號等任務的新數據及高階地球物理模型，正在揭示一個遠比想像中更為複雜的內部結構。
However, new data from missions like Chang’e-6 and advanced geophysical modeling are revealing a far more complex interior.
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。
A landmark discovery highlights a significant hemispheric dichotomy: the Moon’s farside mantle is much drier than the nearside mantle.
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。
This asymmetry suggests that the Moon’s interior is not a uniform sphere but is highly heterogeneous.
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。
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.
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。
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.
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。
By analyzing these compositions, scientists are refining our knowledge of the 'giant-impact hypothesis' and the Moon's cooling history.
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。
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.
