BEIJING.- Astronomers from different countries recalculate the size of the Milky Way using data from a Chinese telescope . , astronomers believed that the radius of the galaxy measured about 50 thousand light years, and that the distance of the Sun from its center would be about 25 thousand light years . There is a clearly defined boundary at the edge of the galactic astral disk, and from there the number of stars falls sharply.
But in recent years, more young stars have been discovered beyond this edge, indicating that the astral disk would extend further than we thought, according to the data compiled by a telescope located in Xinglong District. of Hebei Province, North of China
The Large Spectroscopic Spectroscopic Telescope (LAMOST), of the National Astronomical Observatory (NAO) of the Chinese Academy of Sciences, He can observe about four thousand celestial bodies at a time and has made valuable contributions to the study of the structure of the Milky Way .
At the end of last year, the astronomer OAN Liu Chao counted the stars at the edge of the galaxy using the data of LAMOST and drew a sample of the outer ring of the plan of the galaxy.
Liu discovered that although there are fewer stars, they do not disappear completely 50,000 light-years away from the galactic center, but they can still be found 62,000 light-years away [19659013]. , participated in Liu's investigation. On the basis of their discoveries, they calculate that the radius of the galactic astral disk could reach 100,000 light-years.
Chinese scientists established the world's largest stellar databank based on observations of LAMOST information that they will use to better understand the Milky Way and study evolution galaxies and the universe
