“Céu de origens”: design decolonial como abordagem para a representação de constelações indígenas em planetários

Abstract

Throughout history, Brazilian Indigenous peoples have developed systems of celestial observation that reflect a profound relationship between human beings, nature, and the cosmos. This study proposes an interdisciplinary dialogue between Design and Cultural Astronomy, aiming to value and preserve the astronomical knowledge of Indigenous peoples from a decolonial perspective, through the creation of immersive projections adapted to planetariums, structures designed to simulate the sky. The research analyzed the graphic resources used by Planetarium Kariri, a project developed in the Cariri region of Ceará, as well as different forms of visual representation of four Indigenous constellations: the Rhea, the Old Man, the Northern Tapir, and the Deer. Based on these analyses and the identified needs, illustrations were developed, along with a script and animation storyboard for projection in the planetarium dome, in addition to descriptive and illustrative cards. These materials aim to provide an aesthetic, symbolic, and educational interpretation of Brazilian Indigenous cosmovision, contributing to the strengthening of cultural diversity in scientific spaces. The study highlights the potential of Design as a tool for decolonization and as a mediator between science, art, and tradition, promoting visual experiences that integrate technology and ancestry.
