CTOnews.com, September 17, according to a CCTV report, the Mozi Survey Telescope, which has the strongest optical time-domain survey capability in the Northern Hemisphere, was officially put into observation at the Qinghai Lenghu Astronomical observation Base today (September 17), which will make China's time-domain astronomical research capability reach the international advanced level.

A photo of the Andromeda galaxy taken by this telescope during the trial observation phase was released on the same day, which is also the world's largest high-resolution image of the Andromeda galaxy.

Photo of the Andromeda galaxy taken by the ▲ Mozi Survey Telescope it is reported that this photo of the Andromeda galaxy is superimposed by the Mozi Survey Telescope through a total of 150 exposures in 30 seconds at a time. This is the largest high-resolution image of the Andromeda galaxy captured in the world, which is of great significance for subsequent astronomical research.

The telescope is the largest and most capable telescope in time domain survey in the northern hemisphere. it has a field of view of 2.5 meters and is located in the Leng Lake Astronomical observation Base in Haixi Prefecture, Qinghai Province.

The main mirror diameter of Mozi Survey Telescope is 2.5 meters. By using the international advanced main focus optical system design and active optical correction technology of the main mirror, it can achieve uniform high image quality and very low image field distortion in the range of 3-degree field of view, and is equipped with a 765-megapixel large target surface main focal camera. it has the characteristics of large field of view, high image quality and wide band.

Mozi Survey Telescope has the advantages of large light area, less stray light, high detection sensitivity and strong ability to survey the whole northern celestial sphere every three nights, which is the most powerful equipment for optical time-domain survey in the northern hemisphere. its core scientific objectives are to search and monitor astronomical dynamic events and to carry out time-domain astronomical observation research.

Lou Zheng, chief engineer of the Qinghai Observatory of the Zijinshan Observatory of the Chinese Academy of Sciences, said previously that the current work is to optimize the imaging quality of the telescope, and its pointing and tracking performance still needs to be further optimized. When Mozi is officially put into observation, it can detect some very weak and distant celestial signals, including extragalactic galaxies, galaxy clusters and other celestial signals.

CTOnews.com Note: Qinghai Lenghu Astronomical observation Base is located in Saishten Mountain, Lenghu Town, Mangya City, Haixi Mongolian Tibetan Autonomous Prefecture, Qinghai Province, with an average elevation of about 4000 meters. It is also the only world-class observatory in the Eastern Hemisphere. It was published in the top academic journal Nature in 2021-the Chinese research team published a study entitled "Cold Lake Astronomical Observatory site on the Qinghai-Tibet Plateau" (Lenghu on the Tibetan Plateau as an astronomical observing site).

The base has the conditions of scarce vegetation, thin air and less artificial light pollution, and it is also one of the best observatory sites in Eurasia.
