天王星和海王星可能拥有丰富的岩石,而不是冰, 挑战他们的“冰巨人”标签。 Uranus and Neptune may be rock-rich, not icy, challenging their "ice giant" label.

新的研究表明天王星和海王星 可能是岩石富饶的,而不是冰冷的, 挑战他们传统的“冰巨人”分类。 New research suggests Uranus and Neptune may be rock-rich rather than icy, challenging their traditional classification as "ice giants." 苏黎世大学和行星社的科学家利用与重力和磁场数据相匹配的先进模型,发现以岩石为主的内部观测更加适合,有可能解释其复杂的多极磁场。 Using advanced modeling that matches gravity and magnetic field data, scientists from the University of Zurich and PlanetS find rock-dominated interiors better fit observations, potentially explaining their complex, multi-poled magnetic fields. 该研究以天文和天体物理学形式发表,注意到目前的数据无法确切地证实组成情况,强调未来飞行任务需要澄清行星形成和极端条件下的行为。 The study, published in Astronomy & Astrophysics, notes current data cannot definitively confirm composition, highlighting the need for future missions to clarify planetary formation and behavior under extreme conditions.
