The facility replaced the older Dow Planetarium, which operated from 1966 to 2011.
The two main theaters are named the 'Chaos' and 'Milky Way' theaters, each using different projection technologies.
The architecture consists of two aluminum-clad cones that evoke the image of observatories.
The building was designed to be net-zero energy ready, utilizing geothermal heating and cooling.
It is the first planetarium in Canada to incorporate a digital system that can display the entire observable universe in real-time.
The site includes a permanent collection of meteorites, including rare samples found in Quebec.
The Montreal Planetarium (Planétarium Rio Tinto Alcan) is a world-class astronomy facility featuring two iconic, truncated-cone structures. It houses two distinct high-resolution immersive theaters that utilize specialized digital projection technology for astronomical displays. The facility is part of the Espace pour la vie complex, which integrates scientific and natural history exhibitions. It serves as a research hub for astronomy while offering interactive, hands-on science activities for visitors of all ages. The building design reflects sustainable architecture, achieving LEED Platinum certification. Unlike traditional star-projection systems, its theaters focus on scientific storytelling and artistic visual interpretation of space. It remains one of the largest planetariums in Canada by visitor capacity. The complex is physically adjacent to the Montreal Biodome and Olympic Stadium.
