stars rather than blue main-sequence stars, as in the case of the spiral arms. This finding led Baade to suggest that these galaxies, and also the Milky Way Galaxy, are made of two populations of stars that are distinct in their physical properties as well as their locations. He applied ...

Spectra are key for astronomers to read celestial bodies' chemical compositions, densities, atmospheres and magnetism. From the spectra collected by LAMOST, astronomers have discovered some unusual stars and studied the structure of the galaxy.
Milky Way Galaxy - Structure, Dynamics, Stars: The first reliable measurement of the size of the Galaxy was made in 1917 by American astronomer Harlow Shapley. He arrived at his size determination by establishing the spatial distribution of globular clus
