Galactic archaeology uncovers the dramatic history of our next-door neighbor, the Andromeda galaxy

Research led by the University of Hertfordshire has revealed the dramatic history of Andromeda, our nearest neighboring galaxy. Using state-of-the-art modeling, Professor Chiaki Kobayashi and a team of international astrophysicists have determined details about the galaxy's history through galactic archaeology—an approach that examines the chemical composition of stars and the development of their host galaxy, to reconstruct its past.
