What makes the SKA special is its sheer scale.

SKA项目的特殊之处在于它巨大的体量。

The SKA is a collaboration between 16 countries.

平方千米阵项目是16个国家的合作项目。

Another kind of telescope, the Square Kilometer Array (SKA), promises to help search for technosignatures soon.

另一种望远镜，平方公里阵列(SKA)有望很快帮助寻找“技术签名”。

I know a little ska. How fast is ska?

我知道一点斯卡。 斯卡有多快？

The SKA will use about 110 megawatts when up and running, so power bills will be a significant expense.

当SKA准备好运行的时候，预计会消耗百万瓦特的电。因此，会花费巨大的电费。

Both consortia had constructed precursor telescopes that could be integrated into the SKA itself, and each bid had its advantages.

两支队伍已经建造出了各自的前导望远镜（它本身也可以整合进SKA项目），两边都有各自的优势。

The SKA will join the hunt for gravitational waves-ripples in the structure of space predicted by Albert Einstein's general theory of relativity.

SKA项目将参与到捕获重力波（阿尔伯物·爱因斯坦在其广义相对论中把重力形容为空间结构中的涟漪）的研究中。

When it fully completes, SKA plans to have a lifetime of at least 50 years.

完全完工后，SKA 计划的使用寿命至少为 50 年。

Work has just begun on the largest and most ambitious facility of its kind ever attempted - the SKA Observatory.

有史以来规模最大、最雄心勃勃的同类设施 - SKA 天文台的工作刚刚开始。

Applying that sort of ratio to the SKA, which is designed to work with wavelengths measured in metres, would require a dish thousands of kilometres across.

SKA利用的电磁波波长达到数米之长，如果在其上也应用此类电磁波的话，其直径将达到数千公里之长。

After months of deliberation, the SKA's funding nations announced their decision: that the telescope would be split, and both groups would host a bit of it.

经过数月的深思熟虑之后，向SKA提供资金的国家宣布：这个望远镜将分成两个部分，两支队伍分别主持各自的部分。

With remarkable progress made in space exploration and discovery in recent decades, it's hoped that SKA will be the tool that enables the next major leap forward.

随着近几十年来太空探索和发现取得的显着进步，人们希望 SKA 成为实现下一次重大飞跃的工具。

And that was particularly so in Africa, where the SKA is seen as a good-news story for a continent still struggling to overcome its image as a violent and chronically unstable place.

这一点对于南非来说尤其如此，SKA项目对于这个长期充满暴力和不稳定的大陆来说，无疑是一篇正面新闻报道。

It's got nothing to do with Jamaican music - in this case, SKA stands for Square Kilometre Array, referring to the total collecting area that all the various equipment will take up.

这与牙买加音乐无关——在这种情况下，SKA 代表平方公里阵列，指的是所有各种设备将占用的总收集区域。

When it is fully up and running (by 2024, assuming no big delays) , the SKA will be more than 50 times more sensitive than any other radio telescope, and able to survey the sky thousands of times faster.

当这个项目竣工并投入使用之时（如果没有任何大的耽搁的话，预计2024年完成），SKA项目的灵敏度将是目前已有的射电望远镜的50倍，它可以探测的宇宙范围是目前的数千倍远。

Each of the two SKA supercomputers will be as powerful as the best in the world - as of 2019 - and the system will use enough optical fibre to stretch around the planet - twice.

截至 2019 年，两台 SKA 超级计算机中的每一台都将与世界上最好的超级计算机一样强大，并且该系统将使用足够的光纤绕地球一周——两次。

Overseeing everything is a team of specialists at SKA's headquarters - thousands of miles away in the UK. Next question, then - why have it in two parts, and in places so far away from each other?

监督一切的是 SKA 总部的专家团队——位于英国数千英里之外。下一个问题，那么——为什么要把它分成两部分，而且在彼此相距那么远的地方？
