Galaxy colorâmagnitude diagram. A mock-up of the galaxy colorâmagnitude diagram with three populations: the red sequence, the blue cloud, and the green valley. The galaxy colorâmagnitude diagram shows the relationship between absolute magnitude (a measure of luminosity) and mass of galaxies.
An international team of astronomers finds that that thereâs a large region around the center of our home galaxy thatâs devoid of young stars. Blue stars here represent Cepheid variables, used in these astronomersâ study, plotted on a background drawing of the Milky Way. The orange clump in the center represents the central 8,000 light-years of our galaxy, which appears to have very few Cepheids and hence few young stars. Image via University of Tokyo.
