Square Kilometre Array Telescope

The Square Kilometre Array (SKA) is a radio telescope with around one million square metres of collecting area, designed to study the Universe with unprecedented speed and sensitivity. The SKA is not a single telescope, but a collection of various types of antennas, called an array, to be spread over long distances. The SKA will be used to answer fundamental questions of science and about the laws of nature, such as: how did the Universe, and the stars and galaxies contained in it, form and evolve? Was Einstein’s theory of relativity correct? What is the nature of ‘dark matter’ and ‘dark energy’? What is the origin of cosmic magnetism? Is there life somewhere else in the Universe?

平方公里阵列（Square Kilometre Array，简称SKA）是一座拥有约一百万平方米接收面积的天线射电望远镜，旨在以前所未有的速度和灵敏度研究宇宙。SKA并非单一望远镜，而是一系列不同类型的天线组成的阵列，将分布于广阔的空间。该阵列将被用于解答科学的基本问题及关于自然法则的诸多疑问，例如：宇宙、其中的恒星和星系是如何形成与演化的？爱因斯坦的相对论理论是否正确？‘暗物质’和‘暗能量’的本质是什么？宇宙磁场的起源是什么？宇宙中是否存在其他生命形式？
