AstroFest 2025 astronomy festival is coming to the Planétarium

Astrofest 2025 is coming to Montreal in June

Mars is the star of the ROUGE 2100 exhibition

Montréal, May 20, 2025 — On June 7 and 8, the Planétarium will be all decked for the AstroFest—a free, unifying event to which Espace pour la vie invites you. Whether you’re driven by a budding curiosity or a consuming passion for the cosmos, the AstroFest is sure to win you over with its rich program on the theme of “Mars – Life in Red”. Over the past 5 years, the AstroFest has become THE annual rendezvous for stargazers. During the day, there are scientific activities for the whole family, and on Saturday evening, cosmic buffs are invited to an evening of marshmallows, telescopes, lectures, DJs, and cocktails!

Mars in the spotlight

A planet that has been the stuff of space travel fantasies for centuries, Mars is the star of the ROUGE 2100 exhibition, which will be open free of charge until midnight for the occasion! The red planet, which will be visible in the sky, high above the horizon, from dusk onwards, will also be at the heart of the activities on offer throughout the day. This is a phenomenon that only happens every 26 months! Although we know more about certain regions of the Martian surface than we do about the bottom of the Earth’s oceans, there is still so much to explore on this “neighbouring” planet.

Espace pour la vie 

Protecting biodiversity and the environment is at the heart of the mission of Espace pour la vie, which groups the Biodôme, the Biosphère, the Insectarium, the Jardin botanique and the Planétarium.
