The apogee survey is a large-scale astronomical survey that aims to study the Milky Way galaxy by collecting high-resolution spectra of individual stars. This survey focuses on understanding the chemical compositions, kinematics, and dynamics of stars in our galaxy, providing important insights into the formation and evolution of the Milky Way. Apogee uses a specialized instrument called the Apache Point Observatory Galactic Evolution Experiment (APOGEE) spectrograph to measure the spectra of over 100,000 stars, allowing astronomers to analyze the abundances of various elements and study the structure and history of the Milky Way.
