Pan-Andromeda Archaeological Survey (PAndAS)
is a large-scale astronomical survey using the Canada-France-Hawaii Telescope
The Canada–France–Hawaii Telescope is located near the summit of Mauna Kea mountain on Hawaii's Big Island at an altitude of 4,204 meters , and is one of the observatories that comprise the Mauna Kea Observatory...
The survey is exploring the structure and content of the Andromeda Galaxy
The Andromeda Galaxy is a spiral galaxy approximately 2.5 million light-years from Earth in the constellation Andromeda. It is also known as Messier 31, M31, or NGC 224, and is often referred to as the Great Andromeda Nebula in older texts. Andromeda is the nearest spiral galaxy to the...
(M31) and its neighbour, the Triangulum Galaxy
The Triangulum Galaxy is a spiral galaxy approximately 3 million light years from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598, and is sometimes informally referred to as the Pinwheel Galaxy, a nickname it shares with Messier 101...
(M33). Clues to the formation of these galaxies may lie within the vast space being studied. PAndAS is searching for this history, hence the term "galactic archaeology".
The project is headed by Dr. Alan McConnachie at the Herzberg Institute of Astrophysics
The NRC Herzberg Institute of Astrophysics is the leading Canadian centre for astronomy and astrophysics.Named for the Nobel laureate Gerhard Herzberg, it was formed in 1975 as part of the National Research Council of Canada in Ottawa, Ontario...
(NRC-HIA), and involves over twenty five investigators from that institute, as well as from universites in Canada, France, the United States, the United Kingdom, Germany, and Australia.
