新的分析显示,30至40亿年前的月球磁峰是短暂而激烈的,由于钛富岩融化而没有持续。
Lunar magnetic spikes 3–4 billion years ago were brief and intense, not sustained, due to titanium-rich rock melting, new analysis shows.
对阿波罗-时代月球岩石的新分析显示,月球的磁场大多很弱,但经历了短短而剧烈的高峰,持续了多达5 000年 — — 可能是仅仅几十年 — — 在30至40亿年前。
New analysis of Apollo-era lunar rocks reveals the moon’s magnetic field was mostly weak but experienced brief, intense spikes lasting up to 5,000 years—possibly just decades—between 3 and 4 billion years ago.
这些爆发可能是由于月球深处丰富的岩石融化而引起的, 它们比地球目前的磁场更强大.
These bursts, likely caused by melting titanium-rich rocks deep within the moon, were stronger than Earth’s current field.
早期关于持续强磁场的结论因抽样偏差而被歪曲,因为阿波罗任务降落在富含的火山区域,这些区域代表了罕见的磁场事件.
Earlier conclusions of a sustained strong field were skewed by sampling bias, as Apollo missions landed in titanium-rich volcanic regions that overrepresented rare magnetic events.
未来针对月球南极地区的Artemis飞行任务可能会收集更具代表性的样本,有助于澄清月球的磁史及其对行星适居性的影响。
Future Artemis missions targeting the moon’s south polar region may collect more representative samples, helping clarify the moon’s magnetic history and its implications for planetary habitability.
