Espace pour la vie presents

The 4th edition of the AstroFest

Celebrate the sun in all its splendour!

Espace pour la vie celebrates astronomy with the fourth edition of the AstroFest, the Planétarium’s annual free event for all. For the first time ever, the festival will spread out over two days—June 15 and 16—for twice the fun!


Espace pour la vie – Mathieu Rivard

This year, the AstroFest celebrates the Sun. Did you know that activity on the Sun’s surface is about to reach the peak of its 11-year cycle? 2024 has already given us an extraordinary total solar eclipse and fascinating aurora borealis. And there’s so much more to come!

Dozens of free activities from over thirty partners in the field of astronomy await you! Water rockets, arts and crafts, workshops, lectures as well as sun and star gazing, in a musical atmosphere with face painting, popcorn, and cotton candy!

Prepare for take-off
Intergalactic travelers are invited to the Planétarium, transformed for the occasion into a retro-futuristic spaceport. Embark on an adventure and learn more about astronomy and this magnificent star that is so close to us.
