Chinese astronomers have successfully calculated the mass of the Andromeda galaxy using spectral data from the郭守敬望远镜（LAMOST）and existing observation results of the Andromeda galaxy (M31). According to reports on February 5th, researchers from Yunnan University and other units constructed the largest international star catalog with radial velocity measurements of the Andromeda galaxy. This achievement is of great significance for further understanding the structure and properties of the Andromeda galaxy.
