Arecibo telescope

Earth's most powerful radio signal is the beam from the Arecibo telescope.

地球上最强大的无线电信号来自阿雷西博天文台。

Over time, even without being granted dedicated telescope time, the piggy back SETI receiver managed to scan the entire sky visible from Arecibo.

随时间流逝，即使没有获得专门的望远镜时间，附加式的SETI接收器也能扫描完整个天空。

The current largest operational radio telescope is the 300-meter-diameter Arecibo Observatory in Puerto Rico, but FAST in Guizhou will far surpass that.

目前运行的最大射电望远镜在波多黎各阿雷西博天文台（Arecibo Observatory），直径为300米，贵州的FAST将远远超过它。

Because it is so hard to acquire sufficient telescope time for a sky survey, SETI observations at Arecibo were conducted up to now in the in the piggy-back mode.

因为很难得到充足的望远镜使用时间进行全天调查，如今SETI在阿雷西博的观测采取的是一种附加式的模式。

The instrument platform of the 305-meter telescope at Arecibo Observatory overnight, according to the National Science Foundation.

美国国家科学基金会称，位于波多黎各的直径达305米的阿雷西博射电望远镜设备平台一夜之间坍塌。

This is significant because of the unique geometrical features of the Arecibo telescope: whereas most radio dishes are parabolic in shape, the Arecibo dish is a giant half-sphere dug into the ground.

这非常重要，由于阿雷西博望远镜的独特几何结构：尽管绝大多数的射电望远碟面都是抛物面型的，而阿雷西博的碟面是在地上挖出的一个巨大半球。
