From the calendar

Official source · University of Toronto Mississauga

The Universe extends from the Sun to the most distant regions we can observe. This course explores our Sun, the other stars, the Milky Way galaxy in which our Sun lives, other galaxies that are far outside our Milky Way, and the most distant objects we can observe. In addition, the course presents evidence that everything we observe is just a small fraction of what exists in the Universe. The course content considers how the Universe began and evolved over time and the possibility of life beyond Earth.
