This morning (9th), the main structure of the international space science cooperation project "Capture the Baryon Acoustic Oscillation Signal of the Universe" jointly launched to Brazil, marking that the radio astronomical telescope will begin construction in Brazil.
This telescope will be built in Paraiba State, Brazil next to the Amazon forest. It is a major international cooperation project in the fields of radio astronomy and space science in my country. It is the largest radio astronomy project in South America and the only radio telescope in the world focusing on dark energy research. It is specifically used to observe the widely distributed primitive gas in the universe - neutral hydrogen. By studying its spectral lines, we can understand the distribution of hydrogen in the universe, so as to better understand the structure and evolution of the universe, and help mankind unveil the mystery of the universe structure and dark energy.
It is understood that in addition to detecting important signals from the deep space of the universe, this radio telescope can also detect the movement of small celestial bodies such as satellites and meteorites, and detect possible invasion threats to the earth. The main design and processing of this antenna are all completed by China.
China Electrical and Electronic Network Communications Research Institute Wu Yang:The telescope adopts a double bias structure, and the shape of each place is different. The telescope will be organized and installed in Brazil by the Brazilian side, which requires the installation process and process of the telescope to be as simple as possible. Therefore, we fully learn from the design and manufacturing experience of advanced telescopes in China and adopt a combined panel and space grid structure to solve the problems of batch manufacturing and high-efficiency installation.
According to reports, the main body of the radio telescope shipped this time will set sail from Tianjin Port, and it will arrive in Suap Port in Brazil after nearly two months. The project is expected to be completed in 2026.
