As part of the “24 hours of science” event organised by Science pour tous, the Institute for Research on Exoplanets (iREx) and the Centre for Research in Astrophysics of Quebec (CRAQ) invite you to discover extraterrestrial worlds with our astrophysicists

Our astrophysicists Marie-Eve Naud, Frédérique Baron and Nathalie Ouellette will be your guides on this interstellar journey! (Credit: É. Artigau/A. Philibert)

This activity will include a 30 minute long online presentation (in French) on the iREx YouTube channel during which your students will learn about the multitude of planets that exist in the Solar System and beyond. They will be able to visit these worlds virtually, find out what their environment is like, and whether life could develop there. They can then compare these worlds to our own planet Earth.

After the presentation, our astrophysicists will be happy to answer your students’ questions submitted via YouTube chat.

This 45-minute long activity is aimed at third cycle primary school students (grades 5 and 6), but we welcome students of all age groups. It will take place online on Monday May 16th 2022 at 10:00 am (Eastern Time).

This activity is over, but you can still watch to it on our YouTube channel!


Teachers can optionally register their classes using the following form to receive a reminder and a link to the activity by email.


Registration is not required, however, and everyone will be able to join the event live on our YouTube channel, https://www.youtube.com/exoplanetes. The presentation will also be available for viewing after the initial stream.
