See a light show in each of the two domes of this planetarium to learn about the stars and see some impressive visuals.

The Rio Tinto Alcan Planetarium is the ambitious replacement for the previous Montréal Planetarium, which closed in 2011. Learn about the mysteries of the universe while seated in one of its two aluminium domes.

While most planetariums across the world have one gigantic dome, the Rio Tinto Alcan Planetarium has two. Each dome holds its own star show every day throughout the week. Buy a ticket to see a show in each dome. The shows are each about 20 minutes long, and are screened several times a day.

The first show is a poetic reflection on the mysteries of life and the universe. Watch as the dramatic visual effects take you on a tour from the smallest to the largest things in the universe. Also, listen for the symphonic music of Philip Glass, which soundtracks this show.

The second show is a scientific tour of the stars and planets visible in our skies. Listen as an astronomer guides you through the constellations and planets. This show also features impressive visuals, letting you see the stars and planets featured in the tour up close. Come during two separate seasons to see the show change to fit the constellations in the Montréal sky.

Explore the permanent exhibition, which is spread out over the space between the two domes. Here, you will find a collection of samples from more than 300 meteorites, including two found in the Québec area. Play with the interactive exhibits on the main floor, which teach about the field of astrobiology. Admire the Tyrannosaurus Rex skull that sits near the front of the exhibition.

The Rio Tinto Alcan Planetarium is located in Montréal’s Olympic Park. It lies next to several other attractions, such as the Biodome and the Botanical Garden. Arrive by bus or metro train, which stop less than a block away. Parking is available for an all-day fee.

The planetarium is open year-round.
