中国建造世界上最大的射电望远镜,面积接近30个足球场的大小,这座巨大的射电望远镜项目被命名为FAST,位于贵州省西南部的群山之中。事实上FAST射电望远镜与世界上著名的阿雷西博望远镜类似,在山谷中挖了一个凹形面,把望远镜建造在山谷之中。阿雷西博望远镜目前仍然保持着单面口径的纪录,直径为305米,接近1000英尺,位于波多黎各的山谷中,主要用于监听宇宙中的神秘信号,同时也有天体观测任务。

Beijing (AFP) – China has started assembling the world’s largest radio telescope, which will have a dish the size of 30 football pitches when completed, state media reported as Beijing steps up its ambitions in outer space.

北京(法新社)- 中国已经开始建造世界上最大的射电望远镜,工程完成后面积接近30个足球场的大小,正如中国国家媒体报道的那样,北京加速在外太空的野心。

The five-hundred-metre Aperture Spherical Radio Telescope (FAST) nestles in a bowl-shaped valley between hills in the southwestern province of Guizhou, images posted online show.

500米口径球面射电望远镜(简称FAST)坐落于中国西南省份贵州的一个碗状山谷里。

Technicians began attaching 4,450 triangular-shaped panels to the telescope’s reflector on Thursday, the official Xinhua news agency reported.

新华社官方报道,周四技术工人已经开始拼装望远镜镜面的4450块三角形单元。

FAST will be the world’s largest single-aperture telescope, it said, overtaking the Arecibo Observatory in the US territory of Puerto Rico, which is 305 metres (1000 feet) in diameter.

FAST将会是世界上最大的单孔望远镜,据说,这将超过美国国内波多黎各的阿雷西博望远镜,阿雷西博直径305米(1000尺)。

For years Chinese scientists have relied on “second hand” data collected by others in their research and the new telescope is expected to “greatly enhance” the country’s capacity to observe outer space, Xinhua said.

多年以来中国科学家一直依靠国外的射电望远镜收集数据,也就是“二手”的观测数据。如果新的望远镜落成将会”极大的提高”国家观测深空的能力。

“Having a more sensitive telescope, we can receive weaker and more distant radio messages,” it cited Wu Xiangping, director-general of the Chinese Astronomical Society, as saying.

引用中国国家天文台研究员武向平的话说:”有了更加灵敏的望远镜,我们可以接受到更远、更微弱的射电”

“It will help us to search for intelligent life outside of the galaxy and explore the origins of the universe.”

“这将会帮助我们搜索银河系外的智能生命并探索宇宙的起源。”

Beijing is accelerating its military-run multi-billion-dollar space exploration programme, which it sees as a symbol of the country’s progress. It has plans for a permanent orbiting station by 2020 and eventually to send a human to the moon.

北京正在加速其军事化的花费了数十亿美元的太空探索项目,将这视为国家进步发展的标志。还制定了2020年建立永久空间站的计划并最终将人类送上月球。

The dish will have a perimeter of about 1.6 kilometres, Xinhua said, and there are no towns within five kilometres, giving it ideal surroundings to listen for signals from space.

望远镜周长约1.6公里,并且在其5公里半径之内没有一个乡镇,这是一个完美的无线电环境可以倾听来自宇宙的信号。

The region’s karst topography — a landscape of porous rock fissured with deep crevasses and underground caves and streams — is ideal for draining rainwater and protecting the reflector, it added.

这里的喀斯特地质 — 可以保障雨水向地下渗透,不会在表面淤积而损坏和腐蚀望远镜。

Construction on the telescope started in March 2011 and is scheduled to finish next year, Xinhua said.

望远镜开始建设于2011年3月,预计明年将会建成。新华社报道。

What a joy. Last Oct, the World Bank/IMF announced China has become the world’s largest economy (again). China now has the world most advance radio telescope, longest Great Wall, world sole hi-speed commercial rail/ASBM, largest Internet population, Grand Canal, tallest buildings, longest bridges. USA, please stop comparing yourself to China. US cannot even send an astronaut to space and muddle in past glories.

真是让人开心。去年10月世界银行/国际货币基金组织宣布中国已经成为世界上最大的经济体(再一次)。中国现在拥有世界上最先进的射电望远镜、最长的长城,世界上唯一的高速商业铁路,最多的网民数量,大运河,最高的建筑,最长的大桥。美国,请别再和中国相比。美国现在甚至不能送宇航员上太空并且还迷失在过去的辉煌里。

No nation can prowess and feat like Chinese. We are best people. We will conquer space.

没有一个国家和中国一样有如此的实力和成就。我们是世界上最棒的,我们将会征服宇宙。

This is a Vietnam troll pretending to hail China. In effect, he is fanning the hatred.

这就是一个越南猴子在冒充中国人,实际上这货在煽风点火。

It is a universally good news for science. I wish it is being built in the U.S., but we can’t have every one of those most advanced instruments. Europe has the largest collider. South America has the largest arrayed optical telescope. We still have the four great observatories in space, the Hubble telescope, the kapler infrared telescope, the Chandra x-ray telescope, and the gamma rays telescope. In three years, we will have the next generation large space telescope, the Webster telescope and the largest optical telescope on earth, the Thirty Meter Telescope in Hawaii. If we don’t continue wasting our money in far away places on insignificant trivial matters, we can do many, many more great things that will make our children proud.

这对科学界来说是一个好消息。我希望它建在美国,但是我们不可能拥有每一个最先进的仪器。欧洲有最大的对撞机。南美洲有最大的排列光学望远镜。我们在太空里还有四个最好的望远镜,哈勃望远镜,开普勒红外望远镜,钱德拉x射线望远镜和伽马射线望远镜。在三年内我们将会拥有新一代大型太空望远镜,韦伯斯特望远镜和地球上在夏威夷的最大的光学望远镜。如果我们不浪费我们的钱在无关紧要的的地方,我们可以做到更多更伟大的事情来让我们的孩子为我们感到骄傲。

  3. Keith 20 hours ago4反对 9支持You to fat for buffet, you go home! 10 minute ok?牛皮吹爆了,给你10分钟滚回家去!懂?==================这个完全没翻译对。丫的说的是“你太胖了,不能在这吃自助餐”。其实是个美国笑话,因为在美国很多中国人开餐厅,里面就包括自助餐。美国人会用很烂的英语,那种一代中国移民才说得出来的土鳖式英语说些跟餐厅有关的无厘头语录。跟吹牛皮没半点关系

  4. 这个评论没什么意思?中国的太空梦不会弱于美国!美国就自己陶醉好了!中国会一步一步的实现自己太空梦,在未来中国会到月球采矿!这不是幻想!因为我们需要能源!

  5. 昨天看了NASA发现了几亿光年才能到达的2号地球的报道!发现归发现,什么时候才能到那里,整个人类进化历史连猴子都算上也就那么几百万年!我们造一个飞船向目的地飞行,那得多少代以后到达啊?如果通过虫洞?虫洞是否真的可以穿过时间?万一迷路那就完蛋了?科技什么时候能够跨越星际旅行!得需要特殊的推进燃料能让飞船达到光速!

  6. 我们不说大话,美国的太空望远镜,中国还没有!别把中国夸的太大了,我们受不了,中国是一步一个脚印的不断探索和追赶,你眼红也没用,贬低也没用,中国就是那样在不断前进倒是真的!
