What had led the builders of the pyramids to make a mirror of heaven on earth? Historically diverse cultures of the world as the egyptian, studied the stars through their architecture. An example are the pyramidal constructions of Gizeh, implanted in relation to the cardinal points and to the location of Orion constellation’s stars. This monumental architecture originally funerary, sought to bring their Pharaohs to the Sun King through the height reached in their constructions. Since then, we have talked about the correlation of these works with the stars of the universe as if they were a mirror that reflects the space. Today, a planetarium is a place dedicated to watching recreations of the night sky in various places on Earth and at different times of the year. It consists of a dome-shaped projection screen, and a mobile planetarium projector capable of projecting the positions of stars and planets. So it is thought as a construction to live from the inside, isolating the user from their environment to be encapsulated inside the dome where he is clearly a spectator, and his unique participation is through observation. This type of planetarium is closely linked to the technological advances given over the years, seeking to engage users in a simulated outdoor space/environment. Instead of simulating it, our proposal seeks to materialize that space through architecture. Knowing the fact that the structure is able to generate voids and occupy them, when we talk about “spatial structure” we refer to a structure that holds itself and inhabits the space. As a consequence, the new planetarium was thought to involve the architecture in the user’s experience. In this new planetarium, the introduction of the mirror and its reflection duplicates the void, making the user inhabits the space. This generates the sensation of lack of gravity making the users feel like they are walking on the stars. We propose a visit where the learning is achieved through the planetarium’s experience; located near to the city, the structure represents one point of the Orion constellation (Saiph star), just like the Gizeh pyramids.

How does it work? At the first moment, it is created a complex relationship between the people and the space because the user is surrounded by the sky and its reflection in the mirror. In this way, it’s created the sensation of walking through the SPACE. On the other hand, the planetarium’s floor feature several specifics spots from which it can appreciate different astronomical phenomenons according to the time of the year. The goal is to give the planetarium a didactic function by guiding the people so they know where to observe. The metallic modulated structure helps to frame, through their gaps, different parts of the sky. In that way, it is created a more particular relationship between the people and the space.
