SEGUE Science

The Sloan Extension for Galactic Understanding and Exploration (SEGUE) mined the stellar content of the Milky Way in order to create a detailed 3-dimensional map of the Galaxy. SEGUE ultimately obtained spectra of 240,000 stars in the disk and spheroid, revealing the age, composition and phase space distribution of stars within the various Galactic components. These stellar excavations provide essential clues for understanding the structure, formation and evolution of our Galaxy.
