STARSET_MirrorDwarf planet Ceres is an ‘ocean world’ with sea water beneath surface, mission finds
The dwarf planet Ceres – long believed to be a barren space rock – is an ocean world with reservoirs of sea water beneath its surface, the results of a major exploration mission showed on Monday.
矮行星谷神星长期以来被认为只是一大块贫瘠的太空岩石，但在周一，一项重大探测任务显示，它是一个海洋世界，其表面下蕴藏着大量海水。
Ceres is the largest object in the asteroid belt between Mars and Jupiter, massive enough to be shaped by its gravity, enabling the Nasa Dawn spacecraft to capture high-resolution images of its surface.
谷神星是火星和木星之间小行星带中的最大天体，其质量及引力已经大到足以使NASA“黎明”号飞船能够捕捉到其表面的高分辨率图像。
Now a team of scientists from the United States and Europe have analyzed images relayed from the orbiter, captured about 35km (22 miles) from the asteroid.
一支来自欧美的科学家小组分析了这组从飞行器传来的，在距小行星35km（22英里）处拍摄的图像。
They focused on the 20-million-year-old Occator crater and determined that there is an “extensive reservoir” of brine beneath its surface.
他们的主要关注点在于有2000万年历史的奥卡托陨石坑。他们确定，那里的地表之下有一个“巨量的卤水储藏库”。
