The ENIGMAs School (National and Interamerican School of Geophysics, Meteorology and Astronomy) on Astronomy Didactics was organized by NAEC Argentina members and invited international professors. During this school, an innovative project for teaching the Solar System to deaf and hard-of-hearing students originated, which was later implemented through a UNLP university extension project in 2025. Focused on specific, visually-oriented learning, the workshop provides teachers with concrete tools to promote astronomical concepts using Argentine Sign Language (LSA) and tailored audiovisual resources. This work describes the core activities designed to foster meaningful learning and real inclusion for the deaf community.
