“原始结构望远镜”是什么东西？据说是中国最近几年最伟 ...

这名字听起来很牛

基本就是1人民币当成20美元用。

发个衔接

好像是在贵州还是广西的那个大望远镜吧，还没建好呢

实施八大天文工程确实是大工程。

05年的你也能扒拉出来，有几个已经完成正在使用中了

应该是建在新疆的

不是啊，我记得是利用南方特有的喀斯特地形，跟一个大碗似的，口径有500米呢

维基百科的介绍：
The Primeval Structure Telescope (PaST), also called 21 Centimetre Array (21CMA), is a Chinese radio telescope array designed to detect the earliest luminous objects in the universe, including the first stars, supernova explosions, and black holes. All of these objects were strong sources of ultraviolet radiation, so they ionised the material surrounding them. The structure of this reionisation reflects the overall density structure at the redshift of luminous-object formation.

PaST will consist an array of some ten-thousand log-periodic antennas spread over several square kilometers. It will capture a detailed radio image of the sky in the range of fifty to two-hundred megahertz. The telescope is built on the high plateau of Ulastai in the west of Xinjiang province, a remote area away from most television and radios signals that may interfere the weak 21 cm background signals.

中国与国外专家合作，在新疆建设了一个成本极低的大型射电望远镜阵列The Primeval Structure Telescope，使用的是数以千计的民用电视接收天线和免费的数据处理软件。这个项目牵头人之一是我国的宇宙学家武向平，研究的对象好像是宇宙最初“再离子化”时期的发光物质，红移z值在6到20之间的中性氢辐射

这些年拿得出手的科学成就也不算少，但是没什么人宣传，也就在各种年会上念念

你说的是贵州在建的以洼地为依托的全球最大射电望远镜（FAST），不是楼主说的“原始结构望远镜”(PAST)，两者的功能不同。

谢谢科普，真不懂
