Community-driven Learning
Our goal at AAVSO is to make variable star astronomy accessible to everyone, whether you are interested in observing, research, or just learning why stars vary in the first place. We accomplish this by creating a community full of individuals that are able to help each other. We facilitate this interaction in a wide variety of ways:
- How-to Hours and Webinars - The AAVSO has held and holds free and open-to-all live interactive sessions and webinars on Zoom. These presentations include How to [. . .] sessions, each with a guest instructor demonstrating how to conduct an aspect of astronomy research or observing, webinar in Spanish (un seminario de web, Las Estrellas a tu Alcance) with the guest astronomer presenting their research, Superstar Astronomers episodes, with world-famous gust astronomers presenting on their research, and many more. Many of the astronomer guests also explain how AAVSO observers can become involved in research projects.
- Webinar and other presentation recordings--if you are unable to attend our webinars and other presentations live, we have an archive of all recordings that you can watch at your leisure on our YouTube channel.
- Forums - If you have a question related to observing, instrumentation, or variable stars in general, the forum is the place to ask. The community is very responsive and very willing to help.
- Mentors - As long as you are a member in good standing, you can request more individualized attention through our mentorship program.
- Getting Involved - Our education model is only possible by the valuable efforts of people like you. We encourage you to help in whatever way is right for you.
