China should build its own 12-meter Optical/Infrared Telescope to make up for the shortage of astronomy equipment with large diameter, according to experts.

The new generation of telescope has a design height of 31 meters and a diameter of 12 meters. Once it is completed, it will become the world's largest optical telescope in aperture and help Chinese scientists to verify and research the nature of dark energy and optical gravitational waves. The telescope will also support the detection of extra-solar, earth-like planets, according to experts. 

Since the beginning of the 20th century, Chinese experts have been calling for this project to be carried out. Key technology behind the large-diameter telescope has been in the research phase for many years. 

Currently, the world's largest single-aperture radio telescope under construction in Guizhou has entered the final stage.
