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.

We’ve all heard about ground-based telescopes and space telescopes, but what about telescopes that are flown on balloons? What do they do? How do they work? Why do we use them? In this lecture, Rachel Domagalski will talk about the history of balloon astronomy, as well as some of the science that’s come from balloon telescopes. She will also talk about the development of two very different balloon telescopes, SPIDER and SuperBIT, that’s taking place right here in Toronto.
