Chinese telescope collects largest data set on stars
China has released 11.25 million spectra - keys for understanding the properties of celestial bodies - acquired by the Large Sky Area Multi-Object Fiber Spectroscopic Telescope to astronomers worldwide.
As the world's largest spectral survey telescope, LAMOST marks the world's first spectral survey project to obtain more than 10 million spectra, which will give insights into chemical compositions, densities, atmospheres and magnetism of celestial bodies.
Among the data, there are 9.37 million high-quality spectra, twice the total number of other astronomic surveys internationally. There are also 6.36 million stellar spectra, creating the largest stellar parameter catalog in the world, according to the National Astronomical Observatories of China of the Chinese Academy of Sciences on Friday.
