The Art Gallery of Alberta presents 

Celestial Passage (2023) is an augmented reality (AR) that uses the AGA’s Main Hall as a simulated observation site for viewing North American Aerospace Defense Command (NORAD) satellite data in real-time. Visitors can navigate a data portrait of orbiting traffic amongst artificially-generated angels. This AR is superimposed onto planetary symbols fixed onto the walls of Main Hall, mapped to record Pluto’s entry into the constellation Aquarius. The AR re-presents information to audiences while rendering visible the unseen in the public domain of space.
