Thanks to CTOnews.com netizens for the delivery of clues on the way! CTOnews.com, September 21, CTOnews.com learned from China Telecom official account that on September 20, the first antenna after the if antenna structure of the international large science project square kilometer array radio telescope project (hereinafter referred to as the SKA project), which China participated in the development of, entered the construction phase, which was officially hoisted at the test site of the China Institute of Network Communications.

Picture Source: this is the first if antenna built by SKA since it entered the construction phase. It is another milestone after the Ministry of Science and Technology and SKA Observatory successfully held the online signing ceremony of the physical contribution agreement on SKA if antenna structure at the end of 2022. It marks that China has successfully provided the "antenna solution" for the world in the international scientific project and made another important contribution to the field of international astronomy.

The international large scientific project square kilometer array radio telescope (Square Kilometre Array,SKA), which began in the early 1990s, is the largest comprehensive aperture radio telescope under construction in the history of mankind, and it is a large international scientific project cooperated and jointly funded by many countries. Astronomers and engineers from hundreds of universities and research institutions in about 20 countries around the world participated in the research and development of the project. It is named because the array of radio telescopes has a total receiving area of one square kilometer, the size of 140 football fields. The site of SKA is located in Australia, South Africa and eight countries in southern Africa. In the vast wilderness of about 3000 kilometers, about 3000 antennas will be built to form an one-square-kilometer "giant eye of the earth." it lies still on the surface of the earth, observing the most mysterious sounds in the depths of the universe. According to reports, SKA, as the largest radio telescope in human history, will become the largest and most advanced scientific facility on earth, with a sensitivity increase of 50 times and a sky survey speed of 10000 times higher than the current largest radio telescope array.

Zheng Yuanpeng, chief scientist of China's electricity department, said that SKA will provide an important opportunity for mankind to understand the universe and open a new era for human beings to explore the universe. It is entrusted with the mission of mankind to understand the universe and the mysteries of life, and will devote itself to revealing some basic issues of common concern to all countries and human beings in the world, such as exploring the origin and evolution of the universe and galaxies, and looking for more galaxies. It will also devote itself to revealing and answering questions about "basic forces".

Xu Xiaogang, party secretary of China Telecom Network Communication Research Institute, said that as the lead unit of the SKA antenna structure work package alliance, China Telecom Network Communication Research Institute, together with scientific research and industrial institutions from South Africa, Italy and other countries, will jointly complete the construction task of the SKA antenna structure work package antenna.
