Canadian Participation in the Square Kilometre Array

平方公里阵列（SKA）是一个设计和建造下一代国际射电望远镜的全球项目，工作波长为米到厘米。SKA的收集面积高达100万平方米，分布在3000公里的范围内，将是一个独特的世界设施，也是有史以来最大的科学项目之一。通过利用先进的信息和通信技术，SKA将以比以往任何成像望远镜快1万倍的速度拍摄宇宙的大量图像。它的设计是为了回答我们这个时代的一些重大问题：什么是暗能量？爱因斯坦关于引力的理论是正确的吗？暗物质的本质是什么？我们能探测到引力波吗？第一批恒星和星系是何时以及如何形成的？宇宙磁性的起源是什么？类地行星是如何形成的？在宇宙的其他地方有生命吗？

The Square Kilometre Array (SKA) is a global project to design and build a next-generation international radio telescope operating at metre to centimetre wavelengths. With a collecting area of up to 1 million square meters spread out over 3000 km, the SKA will be a unique world facility, and one of the largest scientific projects ever undertaken. By exploiting advances in information and communications technologies the SKA will image vast volumes of the Universe 10,000 times faster than any imaging telescope ever built. It is designed to answer some of the big questions of our time: what is Dark Energy? Was Einstein right about gravity? What is the nature of dark matter? Can we detect gravitational waves? When and how did the first stars and galaxies form? What was the origin of cosmic magnetism? How do Earth-like planets form? Is there life, intelligent or otherwise, elsewhere in the Universe?
