A Vision for the Future
About Ursa Minors
In November 2023, WAA created Ursa Minors, the club's youth outreach division. The goal of the Ursa Minors is to bring eyes to eyepieces and ignite people's passions in astronomy. Through Ursa Minors, the WAA reaches hundreds every year and introduces many to the world of astronomy. By helping with Ursa Minors, you can bring astronomy to the next generation and beyond.
