Just like the Earth, the Moon is about 4.5 billion years old. It has been and continues to be constantly bombarded by meteorites. Some suggest that this rate of bombardment has remained constant in the past couple of billion years. The Moon’s surface without any substantial atmosphere or tectonic activity serves as a time capsule, helping us detangle Earth’s history. The only way to see if the bombardment rate has changed is to have an age for every single crater, an extremely difficult task using traditional crater dating methods.

This weekend tour introduces families to the wonders of astronomy through an indoor planetarium experience, craft activities for younger visitors and stargazing. Visitors will spend time in both the main building and observatory visiting the 1.88m (74") telescope, learning its history and getting to see celestial objects firsthand (weather permitting).

Join us as we recognize the first International Pride in STEM day with an afternoon of activities and a Science Slam featuring LGBTQ+ speakers. At the Ontario Science Centre, we hope that the International Day of LGBTQ+ People in STEM will help create an accepting STEM environment, improve LGBTQ+ visibility and representation in STEM fields while strengthening the community, improve support and resources for LGBTQ+ people in STEM and encourage LGBTQ+ youth to continue with STEM subjects and pursue their dreams. 

(with telescopes! weather permitting... and astronomically-themed music from the 17th and 18th centuries)

This July, in celebration of the first international LGBTQ STEM Day, The Story Collider will present five true, personal stories about science from members of the LGBTQ+ community.
