🎬 官方拓展视频:Moon Mystery (木卫二欧罗巴之谜)

Jupiter is the largest planet in the solar system.
木星是太阳系中最大的行星。
🪐 背景与视听导读 · Europa (木卫二)
木星是太阳系中体积最大的行星,已发现的卫星多达79颗以上。其中,木卫二(Europa,欧罗巴)自1610年被天文学家伽利略发现以来,一直令科学家着迷。它比地球的月球略小,整个表面被厚达数十公里的水冰包裹。科学家坚信,冰壳下方隐藏着一片辽阔深邃的液态咸水海洋,其水量甚至超越地球所有海洋的总和!在地球极寒深海的严酷环境中都能发现生命的存在,因此木卫二被视作太阳系中最有可能孕育外星生命的星球之一。未来科学任务正计划派遣钻探机器人(robot)登陆木卫二,解开冰封海洋之谜!
