科学家发现了海王星以外的三组不同的冰层体, 重新塑造了对太阳系形成的看法。 Scientists uncover three distinct groups of icy bodies beyond Neptune, reshaping views on solar system formation.

来自佛罗里达中部大学的研究人员发表了《自然天文学研究》,为外太阳系的形成提供了新的见解。 Researchers from the University of Central Florida have published a study in Nature Astronomy that offers new insights into the formation of the outer solar system. 通过分析跨尼普敦天体(TNOs)和中世纪天体,它们发现了三个由早期太阳系冰层保留线形成的不同组别。 By analyzing trans-Neptunian objects (TNOs) and centaurs, they discovered three distinct groups shaped by early solar system ice retention lines. 该研究使用James Webb空间望远镜,将这些群体的构成与形成条件联系起来,揭示了TNOs光谱信号在接近太阳时的变化。 The study, using the James Webb Space Telescope, links these groups' compositions to their formation conditions, revealing how TNOs' spectral signatures change as they move closer to the sun.
