65米射电望远镜落成China unveils huge radio telescope

A 70-meter-high radio telescope, the fourth largest in the world, is unveiled at Shanghai Astronomical Observatory on Oct 28, 2012. The radio telescope, which will be used for space observation, differs from optical ones in that they use radio antennae to track and collect data from satellites and space probes.

2012年10月28日，在上海佘山脚下，总体性能名列全球第四、亚洲第一的上海70米高的射电望远镜正式落成。射电望远镜和擅长于“看”的光学望远镜不同，它用于接收来自于宇宙中遥远天体的微弱的电磁波信号，用射电探测方法就能“捕捉”到这些天体。
