Stargazers have made defining astronomical discoveries for 100 years using a Canadian telescope sitting on an unsuspecting hill in Saanich, and now Parks Canada has recognized it as a national historic site.
The Dominion Astrophysical Observatory, which for years was home to the Centre of the Universe at 5071 West Saanich Rd., had its famous Plaskett telescope installed on May 6, 1918, which began a wave of research at the observatory that propelled Canada onto the world stage of astrophysics.
The telescope was the countryB次元官网网址檚 first major publicly funded B次元官网网址渂ig scienceB次元官网网址� project, and for over 30 years enjoyed the status of being one of the worldB次元官网网址檚 largest telescopes. Major discoveries, including John Stanley PlaskettB次元官网网址檚 work on the structure of the Milky Way, research into binary stars, studies of stellar X-ray sources and stellar-mass black holes are some of the accomplishments made at the facility.
In recognition of the centennial anniversary, Parks Canada unveiled a plaque Thursday morning which recognized the observatory as a national historic site, a well-deserved honour, noted DAO director Dr. Dennis Crabtree.
B次元官网网址淚t set Canada on a path and really put us on the map,B次元官网网址� he said.
Crabtree has worked on and off with the Plaskett telescope since he began studying astrophysics in the late B次元官网网址�70s. He has also worked intermittently at some of the worldB次元官网网址檚 most powerful and modern telescopes, including those in Baltimore, Hawaii and Chile.
Comparing those telescopes with the Plaskett would be like B次元官网网址渃omparing a 20-year-old sprinter with an 80-year-old at a 100-metre dash,B次元官网网址� but that the foundational work the Plaskett has allowed in astrophysics is monumental.

As an example, he noted that some measurements initially conducted by the telescopeB次元官网网址檚 namesake remain relevant, including the mapping of the Milky Way. B次元官网网址淚tB次元官网网址檚 still the iconic diagram used in text books, and the shape and form is essentially what Plaskett drew in 1934.B次元官网网址�
While the telescope is no longer on the forefront of technology, it is still used every night by students, for longer-term monitoring, and watching asteroids.
B次元官网网址淚tB次元官网网址檚 important work, but just not making the front page news,B次元官网网址� Crabtree said.
Visitors are welcome to visit the Centre of the Universe area at the observatory, but they can also see an exhibit about the ObservatoryB次元官网网址檚 history at a special, free display going up on the first floor of the Royal BC Museum starting Friday. Included will be a timeline of the observatoryB次元官网网址檚 accomplishments and a small-scale model of the Plaskett telescope built in 1914.
