The LAMOST DR6 catalogue of stellar parameters has currently the world’s most complete sky coverage and the largest survey volume and sampling density, providing a powerful and basic data foundation for studies of the Milky Way, galaxy formation, and evolution, according to China’s national astronomical observatories.

A total of 769 clients from 124 institutions and universities in the US, Germany, Belgium, and Denmark are using LAMOST’s data for cutting-edge research. Some achievements have been made on the formation and evolution of the Milky Way, stellar physics, and special celestial search, China Central Television (CCTV) reported.
