火星有与地球相似的坚固内核 利用来自1300多座地震的数据 发现了火星的内核 Mars has a solid inner core similar to Earth's, discovered using data from over 1,300 marsquakes.

科学家们发现火星有与地球相似的坚固内核 利用美国航天局 InSight登陆器的数据 记录了1300多起地震 Scientists have discovered that Mars has a solid inner core similar to Earth's, using data from NASA's InSight lander which recorded over 1,300 marsquakes. 核心半径约600公里,周围环绕着一个液态外核,这表明火星曾经有像地球那样的磁场。 The core, with a radius of about 600 km, is surrounded by a liquid outer core, suggesting Mars once had a magnetic field like Earth's. 这一发现为火星的进化历史和内部结构提供了至关重要的见解。 This finding provides crucial insights into Mars' evolutionary history and internal structure.
