The Milky Way Galaxy as a research area encompasses the observational and theoretical study of the structure, dynamics, composition, and evolution of our home galaxy as an astrophysical system. It integrates stellar populations, interstellar medium phases, dark matter halo properties, star formation processes, central supermassive black hole activity, and Galactic chemical evolution. Research focuses on mapping its spiral structure, bar and bulge morphology, disk thickening, satellite interactions, and accretion history using multiwavelength surveys, astrometry, spectroscopy, and numerical simulations. This area provides a detailed laboratory for testing models of galaxy formation and evolution under ΛCDM cosmology, leveraging precise distance scales and resolved stellar populations unique to the Milky Way.
This NASA/ESA Hubble Space Telescope image features a dusty yet sparkling scene from one of the Milky Way's satellite galaxies, the Large Magellanic Cloud. The Large Magellanic Cloud is a dwarf galaxy situated about 160,000 ...
