Starfest 2025 to Explore the Mysteries of Dark Matter and Dark Energy
Canada’s largest astronomy gathering returns August 21–24 near Mount Forest.
Starfest, Canada’s largest annual star party and astronomical conference, will return to Riverplace Campground just north of Mount Forest from August 21 to 24, 2025.
Now in its 42nd year, the event is organized by volunteers from the North York Astronomical Association (NYAA), drawing astronomy enthusiasts, professionals, and amateur stargazers from across the country.
This year’s theme, "Dark Matters", focuses on the elusive subjects of dark matter and dark energy—phenomena that remain among the most enigmatic in modern astrophysics. Though neither can currently be observed directly, both are widely believed to play a crucial role in shaping the structure of the universe, inferred through their gravitational effects on galaxies and visible matter.
The 2025 conference will feature keynote lectures by leading astrophysicists, including Dr. Ting Lee, Dr. Mike Hudson, and Dr. Liza Sasonova, alongside presentations from a wide range of speakers covering diverse astronomical topics.
In addition to lectures and discussions, Starfest will offer a variety of activities designed to engage participants of all ages and skill levels, including:
Night sky tours
Astrophotography workshops
Telescope construction demonstrations
Kidsfest, a science program for children
Astrophotography contests, regarded as among the most prestigious in Canada
Starfest has grown steadily since its inception, earning a reputation as a hub for public education, scientific exchange, and astronomical outreach. According to the NYAA, the event aims to foster a deeper understanding of the universe and encourage participation in observational astronomy.
