The AAVSO is building a suite of tutorials and documents aimed at those with absolutely no experience with variable stars and very little astronomical experience of any kind. These tutorials walk you through a basic concept of variable star science and then provide a list of challenges to apply the concepts.
Contact us when you have completed a tutorial and we will mail you a certificate.
If you are looking for an easy introduction to variable stars, check out our Variable Star Astronomy curriculum . It was originally written for high-school and undergraduate science classes but is also an excellent introduction for anyone who doesn't know what a variable star is.
