China Unveils New Radio Telescopes in Antarctica
China Launches Radio Telescope in Antarctica
WUHAN, China (AP) — China has launched the “Three Gorges Antarctic Eye,” a 3.2-meter aperture radio telescope, at its Zhongshan Station in Antarctica. The project, developed by China Three Gorges University (CTGU) and Shanghai Normal University (SHNU), aims to bolster China’s capabilities in intercritical astronomy.
The telescope officially began scientific observations of neutral hydrogen and ammonia molecules in the Milky Way galaxy, CTGU told Xinhua on monday, April 7, providing data to help understand interstellar gas dynamics and star formation.
Zhang Yi, a lecturer at SHNU and member of the Chinese expedition team, said the device will expand radio observation to low-frequency millimeter waves, fostering technological advancements for future intercritical astronomy tools. He added that the project overcame key technical hurdles in constructing an intercritical observatory,laying the groundwork for a future submillimeter wave telescope.
Zeng Xiangyun,a lecturer at CTGU,noted the extreme cold and strong winds in Antarctica posed important challenges for the telescope’s growth and installation.
China also plans to install a new telescope array, the Astronomy Domain tianmu antarctica, near the South Pole. The prototype has already completed a trial operation. The project is expected to consist of 100 small-diameter telescopes with a wide field of view, each covering 10,000 square degrees of the sky.
CTGU and SHNU have been collaborating as 2023 to address challenges in astronomical observations in extreme environments. Scientists have adapted equipment to withstand sub-zero temperatures and storm-force winds.
He Weijun, party chairman at CTGU, emphasized the project’s importance, stating, “The success of the operation of ‘Three Gorges Antarctic Eye’ shows the achievement of our university related to polar research equipment.”
the construction of the “Three Gorges Antarctic Eye” underscores China’s commitment to astronomical research,leveraging Antarctica’s unique conditions for cosmic observation and strengthening the nation’s scientific infrastructure in the region.
“This reflects the enthusiasm of Chinese scientists to achieve a new level in science and technology, as well as the vital role of the university in national innovation,” He added. CTGU plans to send scientists to Zhongshan Station for further scientific expeditions once the telescope’s operation stabilizes.
China is expanding its astronomical capabilities, utilizing the pure Antarctic atmosphere to observe infrared and millimeter waves.
Previously, researchers from the National Astronomical Observatory (NAOC) under the Chinese Academy of Sciences (CAS) identified a high-speed star ejected from the M15 globular cluster, providing evidence for a medium-mass black hole. The findings were published in the journal *National Science Review*.
