China's wide-field telescope, which is capable of surveying the entire sky from the Northern Hemisphere, has revealed a stunning image of the Andromeda Galaxy on Sunday. The photo is currently the world's largest field-of-view image of the Andromeda Galaxy with a high resolution. 

Measuring 2.5 meters in diameter, the Wide Field Survey Telescope (WFST) is now the largest time-domain survey facility in the Northern Hemisphere. The telescope was officially put into operation in northwest China's Qinghai Province on September 17.
