Our annual Observational Challenge is back!
During the months of December 2024 and January 2025, we invite you to discover the sky. There are so many beautiful things to see when you take the time to look up! With this challenge, you will have the chance to observe the Moon in several of its phases, the planets Venus, Saturn, Jupiter and Mars as well as identify several stars and constellations!
Here you will find information on the different observations to be made and the best times to do them.
SPECIAL INVITATION TO TEACHERS AND EDUCATORS!
Register for our challenge to receive additional educational material that will allow you to complete this Challenge with your students and learn more about the celestial objects and phenomena. You will also be introduced to exoplanets! This activity is presented in collaboration with the Trottier Institute for Research on Exoplanets in Montreal!
You can download the Challenge Sheet to note your observations. If you're lucky with the weather and manage to fill it, you can use another one or any simple observational journal.
