Become a volunteer

Want to make your contribution to the public observatory of tomorrow? Find out more on what you can do as a volunteer at Cozmix.

Cozmix - as the visitor center of the public observatory Beisbroek - has the main mission to popularize astronomy, meteorology, space and related sciences and technology to a diverse public.

Ever since its creation in 1984, the proper functioning of the people's observatory has relied on the passionate commitment of its volunteers. Together with the expansion of the visitor center Cozmix, the volunteer work force was further expanded into a dedicated team of employees.

Due to the continuing and increasing success and the great variety of activities we offer, we more than ever need enthusiastic volunteers to strengthen our team!
