The Centre of the Universe

The Dominion Astrophysical Observatory is a designated National Historical Site. Its original instrument, the Plaskett Telescope was the largest operational telescope in the world when it started observations in 1918. It is still used nightly for scientific research. Tour the telescope and learn the history of this amazing machine that mapped the Milky Way Galaxy. The Centre of the Universe offers the unique experience of visiting the historic Plaskett telescope. We also have our exhibit gallery, complete with planetarium showing the stars and full dome movies, virtual reality experiences, kiosks, and more. Currently our winter hours are in place. During the cruise season we open for exclusive onshore excursions.
