The Pan-Andromeda Archaeological Survey (PAndAS) is an astronomical survey designed to explore, in unprecedented detail, the structure and content of the nearest large galaxy to the Milky Way: the Andromeda Galaxy (M31) and its close neighbour, the Triangulum Galaxy (M33). Hidden within the vast volumes explored by PAndAS lie remnants of — and therefore clues to — the formation of these galaxies. While there might be 400 billion or so galaxies in the Universe, there are only 2 galaxies — Andromeda and Triangulum — whose history can be revealed to us in this level of detail through the study of their "galactic archaeology".
PAndAS is led by Dr. Alan McConnachie at NRC-HIA, and uses the unique capabilities of the MegaCam/MegaPrime instrument on the 3.6m Canada-France-Hawaii Telescope. The project involves more than 25 co-investigators, at NRC-HIA, and at universities across Canada, France, the USA, the UK, Germany and Australia.
