麻省理工学院研究人员通过分析发现于南极洲Dominion Range山脉的陨石DOM 08006,揭示了太阳系早期存在的强大磁场。1研究团队对该陨石中最古老的矿物颗粒——钙铝富包裹体进行了分析,这些包裹体形成于太阳系形成后的前200000年内。1根据研究结果,早期太阳系的磁场强度估算为150至600微特斯拉,约为地球现今磁场的3至12倍。1
这一发现改进了科学家对太阳系起源过程的理解。1研究表明,磁力与重力共同作用,促进了气尘云向太阳和行星盘的转变。1研究团队负责人Benjamin Weiss表示:"这个从球形云到原行星盘的过渡,是太阳系历史上最重要的事件之一。"1这项研究已发表在《美国国家科学院院刊》2026年第123卷第36期,并获得了美国航天局(NASA)的部分支持。1
Researchers at the Massachusetts Institute of Technology have identified evidence of a strong magnetic field that existed during the first 200,000 years of Solar System formation by analyzing the oldest mineral grains found in a meteorite discovered in Antarctica.1 The meteorite, designated DOM 08006, was found in 2008 in the Dominion Range of Antarctica.1 Within this ancient rock, scientists examined calcium-aluminum-rich inclusions (CAIs), which formed during the Solar System's earliest period.1
The study estimates that the early Solar System's magnetic field strength ranged from 150 to 600 microtesla, approximately 3 to 12 times stronger than Earth's present-day magnetic field.1 According to the research team, this magnetic force worked in tandem with gravity to facilitate the transformation of a spherical cloud of gas and dust into the protoplanetary disk, a critical transition in Solar System history.1 Benjamin Weiss, a researcher involved in the study, stated: "This transition from a spherical cloud to a protoplanetary disk is one of the most important events in the history of the Solar System."1 The findings, supported in part by funding from the National Aeronautics and Space Administration (NASA), were published in the Proceedings of the National Academy of Sciences in September 2026, Volume 123, Issue 36.1
