美航天局发布“帕克”太阳探测器首批成果
美航天局 “帕克”太阳探测器 成果
2019/12/30
美国航天局4日发布了“帕克”太阳探测器的首批研究成果，这些对太阳的近距离观测结果有望为全新的太阳物理学提供证据。当天在线发表在英国《自然》杂志上的4篇论文，根据“帕克”太阳探测器前两次近日飞行的观测，首次描述了太阳风中磁场方向的快速翻转现象、快速旋转的太阳风、宇宙尘埃被逐渐气化的区域和空间天气事件的起源等。

早期月球或曾拥有大气层
大气层 行星大气层
2017/10/10
如果穿梭回35亿年前并抬头遥望夜晚的天空，你会看见月亮周围的大气层。尽管现在它只保留了稀薄的团团气雾，但最新计算表明，大规模火山爆发释放了足够热的气体，从而创建了花费7000万年才耗散掉的大气层。相关成果日前发表于《地球与行星科学通讯》。
