Parks after Dark: How Do We Know That?

Saturday, January 23, 2020
6:30 p.m. – 7:30 p.m.
ZOOM Webinar – Register Here.
We often hear scientists talk about stars and other celestial bodies with a puzzling level of familiarity – how do we know how hot they are if we can never measure it directly over the vastness of space? How do we know what they’re made of, and how much they weigh? How did we discover how far away they are? How can we know so much about these objects when we have never touched them directly?
Join a Park Interpreter and special guests from the Royal Astronomical Society of Canada, for this look at how scientists can figure out a tremendous amount of information based on the only thing we can get from these objects – the light they emit.
