NASA专家 15年内 另一个地球
2015/1/12
国外媒体报道，近日，天文学家发表了一个突破性的研究进展：利用开普勒空间望远镜，他们新发现了8颗可能适合生命存在的行星，从而使这类行星的总数量达到了1000个。不过，我们是否有机会利用太空望远镜去了解这些行星的更详细情况？或者有朝一日，前往探访这些行星呢？

新的一年是制定长期计划的最佳时机，而美国宇航局（NASA）似乎已经一头扎进制定计划的“深渊”当中。12月20日，该局的天体物理学部门发布了未来空间任务的愿望清单——对今后30年，甚至更远期进行了规划。
美国航天局(NASA)的宇宙飞船获得的新证据证实了长期以来的一项假说，即水星极地地区存在大量水冰。这一发现将帮助科学家们了解水星，并且有可能揭示地球的起源。刊登在美国《科学》周刊上的有关这项发现的三篇文章（论文一论文二论文三）说，NASA的“信使”号探测器环绕这颗炎热、多岩石的行星运行了一年半，发现了与纯水冰相符的氢元素。尽管水星是距离太阳最近的行星，不太可能存在冰，但证据表明，这颗小小的行星两极...
