ARAn international team of astronomers created the most detailed map of the Andromeda galaxy (M31) using data from NASA's Hubble Space Telescope. The project involved analyzing over 600 images captured in visible light, ultraviolet, and infrared wavelengths. Two main studies were conducted: one focused on the spiral arms and star formation rates, while the other examined the diffuse gas surrounding the galaxy through the MIGA project. Researchers used Hubble's spectrograph to analyze light from 43 distant quasars behind Andromeda, measuring how the gas absorbed radiation. This allowed them to identify millions of individual stars and stellar clusters across vast regions of the galaxy. The study highlights the importance of mapping individual stars to understand the galaxy's formation history.
