Mont-Mégantic Popular Astronomy Festival - in french

The Astronomy Festival is a unique occasion to allow yourself to become passionately inspirered by the stars. Dedicated to the public, this great celebration of the sky will help you discover a whole new approach toward nighttime. In addition to a pleiad of fascinating activities, the Festival is the only time of year that gives public access to Mont-Megantic research Observatory at night. It’s not everynight that you are permitted to take a peek at the sky through the most performing telescope of the country.

Mont-Megantic Observatory will be open 3 nights, July 4-5-6 2024. The evening starts with a conference (in French).  You can then take a shuttle to the summit to reach our 2 observatories : Mont-Megantic Observatory where you can listen to as astronomer and observe if the sky is clear, and the Popular Observatory where our guides are waiting to share their passion!

Let’s meet in the Universe!

2024 Theme : poussières d'étoiles (dust star)

Did you know that the atoms that compose you were formed in the heart of the stars? This major discovery of the 20th century, so well shared by Hubert Reeves, changed the way we look at the Universe and ourselves. We now know that our cosmic bonds are even more numerous! As the famous popularizer wrote, «the history of the Universe is our history».  Discover with us the secret links that unite us to the cosmos.


If the sky is cloudy : all activities are held as scheduled.  There will be a guided tour of the Observatory (in French) and a presentation called Télescope spatial Webb : dernières nouvelles in the Popular Observatory
