About

The Paul-Baumann-Sternwarte is a public observatory near Mainz, dedicated to astronomy education and community engagement. Founded in 1984 by the Astronomische Arbeitsgemeinschaft Mainz, the observatory honors Paul Baumann, a local politician and amateur astronomer whose passion for the stars inspired the group’s formation in 1961. Located in Klein-Winternheim, just southwest of Mainz, the facility offers regular observation evenings, solar viewing sessions in summer, and telescope consultations—all free of charge. Equipped with a 30 cm aperture telescope and computer-guided tracking, the observatory enables visitors to explore celestial phenomena with expert guidance. It plays a vital role in promoting science literacy among children, students, and adults, often collaborating with schools and hosting events during astronomical milestones. The Paul-Baumann-Sternwarte stands as a beacon for amateur astronomy in the region, combining technical precision with public outreach.
