China has unveiled the Three Gorges Antarctic Eye telescope in Antarctica.

About the Three Gorges Antarctic Eye Telescope

The Three Gorges Antarctic Eye is a 3.2m wide radio/millimetre-wave telescope located at China’s Zhongshan Station in Antarctica.
It was developed by China Three Gorges University (CTGU) and Shanghai Normal University (SHNU).
This telescope can detect radio waves and millimeter waves, types of invisible light, allowing scientists to study phenomena like neutral hydrogen and ammonia molecules, essential for understanding star formation and gas movement in space.
Unlike most telescopes, it works with both radio and millimeter waves, providing a more comprehensive view of space.
It is built in one of the harshest environments on Earth, with operating temperatures below -60°C and strong winds, making construction particularly challenging.
