Pan-Andromeda Archaeological Survey

Pan-Andromeda Archaeological Survey (PAndAS) was a large-scale astronomical survey using the Canada-France-Hawaii Telescope. The survey captured data from over 400 square degrees for 226 hours from 2008 to 2012.^[1][2]

The survey explored the structure and content of the Andromeda Galaxy (M31) and its neighbour, the Triangulum Galaxy (M33). Clues to the formation of these galaxies may^{[clarification needed]} lie within the vast space being studied. PAndAS searched for this history, hence the term "galactic archaeology".^{[citation needed]}

The project was headed by Dr. Alan McConnachie at the Herzberg Institute of Astrophysics (NRC-HIA), and involved over twenty five investigators from that institute, as well as from universities in Canada, France, the United States, the United Kingdom, Germany, and Australia.^[3]
