Astronomy Ireland is the largest national astronomy club in the world relative to population and we publish a full-colour 48-page magazine that is posted directly to members every month. Founded in 1990, in 20 years Astronomy Ireland has grown to over 12,000 members in 2010. Our aim is to promote astronomy, space interest and education in Ireland. We achieve this aim by holding talks, lectures, observing sessions and other events nationwide, and through our magazine, Astronomy & Space. The magazine includes, amongst other things, news, letters, book reviews, reader's photo gallery and details on what to see in the sky during the month. Membership also entitles you to concession rate admittance to our public lectures. In addition, members can attend telescope nights on clear Friday and Saturday evenings. You do not need to own a telescope to be a member, everybody is welcome to join. We also run Astronomy Classes for Beginners twice per year in various locations throughout the country. Members are also entitled to a discount on the course fee.
