【综合报道】10月27日消息,当地时间10月26日,NASA宣布,在阳光照射下的月球表面探测到了水分子,并且从结果表明月球的水冰含量或比预期多,存在地点也比预期广。NASA天文物理部门主任Paul Hertz在新闻发布会上称,这一发现表明,水可能分布在月球表面的任何地方,而不仅限于月球上寒冷或阴影的地方

【综合报道】10月27日消息,当地时间10月26日,NASA宣布,在阳光照射下的月球表面探测到了水分子,并且从结果表明月球的水冰含量或比预期多,存在地点也比预期广。

NASA天文物理部门主任Paul Hertz在新闻发布会上称,这一发现表明,水可能分布在月球表面的任何地方,而不仅限于月球上寒冷或阴影的地方。

据悉,这些水分子是在月球南半球的克拉维斯环形山发现的,由美国航天局的SOFIA(平流层红外天文台)所探测到,SOFIA是一个由波音747SP改装的天文台,飞机上架设了直径2.69米的望远镜,该望远镜能够捕捉到水分子的特定波长。SOFIA飞行高度高达13716米,高过地球大气层中99%的水蒸气,从而能够更清晰地看到宇宙。

科学家们认为,这些水很可能“夹在”月球表面的颗粒之间,从而保护它免受月球环境的影响。

外媒报道称,NASA研究人员认为,月球上之所以会有水形成是由于太阳风直接打在月球表面,其中的氢原子与相关物质作用先形成氢氧基,随后又形成水。

“我们使用SOFIA望远镜首次确认了阳光照射下的月球表面有水存在。 我们尚不知道是否可以将其用作资源,但是了解月球上的水对我们的阿尔忒弥斯探索计划至关重要。”NASA官员NASA局长Jim Bridenstine在社交平台上如是说。
