中國(guó)正在建造全球最大的射電望遠(yuǎn)鏡，目的之一是搜尋外星生命的跡象。

據(jù)中國(guó)官方媒體新華社報(bào)道，這個(gè)名為FAST的500米口徑球面射電望遠(yuǎn)鏡，將超過美國(guó)的同類型望遠(yuǎn)鏡。波多黎各的阿雷西博天文臺(tái)望遠(yuǎn)鏡直徑僅300米。

中國(guó)軍方主導(dǎo)的這一太空項(xiàng)目從2011年3月開始建造FAST，投資約為2億美元，預(yù)計(jì)將在今年晚些時(shí)候完工。

據(jù)新華社報(bào)道，完工之后，這個(gè)宏大的工程項(xiàng)目能夠監(jiān)測(cè)到數(shù)百億光年之外的無線電信號(hào)以及可能存在的生命跡象。

巨大的望遠(yuǎn)鏡肯定要占用大量的空間，因此，中國(guó)在2月16日宣布，將搬遷西南省份貴州省的9000名居民。

新華社報(bào)道了搬遷計(jì)劃，并指出為了“保護(hù)”望遠(yuǎn)鏡，所有居民必須全部遷出。搬遷居民可以獲得相當(dāng)于1838美元的補(bǔ)償金。

中國(guó)最近頻頻進(jìn)行居民搬遷工程。例如，為了籌備2008年奧運(yùn)會(huì)，北京搬遷了成千上萬的居民。此外，為了建造大型基礎(chǔ)設(shè)施項(xiàng)目，如湖北省的三峽大壩，中國(guó)政府還曾實(shí)施了三峽移民工程。（財(cái)富中文網(wǎng)）

China is building what will be the largest radio telescope in the world in a hunt for signs of alien life.

Measuring some 500-meters, the Aperture Spherical Telescope, known as FAST, will well surpass a similar model in the United States, according to the Chinese state news agency Xinhua. Puerto Rico’s Arecibo Observatory is only 300 meters in diameter.

The country’s military-led space program began construction of FAST in March 2011 with an investment equal to $200 million, and it should be done later this year.

Once completed, the massive engineering project will be able to detect radio signals—and maybe signs of life—from as far as tens of billions of light years away, according to Xinhua reports.

A telescope that big certainly takes up a lot of space, so China announced Tuesday that it’s relocating 9,000 residents in the southwest province of Guizhou to make way.

Xinhua reported on the planned displacement, noting that the residents will be uprooted for the “protection” of the telescope. The residents who evacuate will receive a subsidy equal to $1,838.

China has quite a recent history of displacing its own people. It famously uprooted hundreds of thousands of residents in Beijing in preparation for the 2008 Olympic Games. It’s also forced the evacuation of its citizens to make room for giant infrastructure projects like the Three Gorges dam in the Hubei province and to—seemingly—rescue people from areas of entrenched poverty.
