San Antonio’s Pearsall Park has been reimagined as a monumental, scaled representation of our solar system with the unveiling of “Ujuālnān (Grand Sky),” a public sculpture commissioned by the City of San Antonio. The artwork, created by Doroteo Garza, features ten planetary sculptures placed throughout the park at a scale of 1:11 billion, inviting visitors to contemplate their place in the cosmos and their relationship with the natural world.
The project, rooted in the history and cosmology of the region’s original Coahuiltecan inhabitants, draws its name, Ujuālnān, from the Pajalate language, meaning “Grand Sky.” Garza explained that the San Antonio River and its surrounding areas were historically known as Yanaguana, and the Coahuiltecan creation story positions Yanaguana as the Milky Way at the center of the universe. The installation aims to foster reflection on humanity’s connection to both the landscape and the vastness of space.
Sculptural Details and Artistic Inspiration
Each planet is represented by a unique sculpture, incorporating diverse materials and artistic elements. The Sun takes the form of a sundial, while the Earth sculpture features a ceramic plaque simply stating, “You Are Here.” Perhaps most striking is the Saturn sculpture, adorned with a metal ring inscribed with lyrics from the song “I wish I could carry you with me into the eternal, living in the happiest moments” by the Michigan punk band Cloud Rat. Garza shared that this inclusion was inspired by a dream his mother had, envisioning Saturn with writing on its rings.
The Pluto sculpture, positioned 1,539.33 feet from the Sun sculpture at the park’s edge, is accompanied by a laser-cut metal screen depicting a galactic spiral and imagery derived from Coahuiltecan traditions. Materials used throughout the multipart sculpture were sourced locally, including handmade mosaic tiles from Heye Mosaics.
Astrophysical Collaboration and Scientific Accuracy
Garza collaborated with Chris Packham, a professor of astrophysics at the University of Texas at San Antonio, to ensure the scientific accuracy and logistical feasibility of the large-scale installation. Dr. Packham assisted with scaling the sculpture throughout the park, bringing his expertise in active galactic nuclei, black holes, and infrared instrumentation to the project. Packham also holds a visiting professorship at the National Astronomical Observatory of Japan, according to his personal website.
The collaboration highlights the intersection of art and science, bringing complex astronomical concepts to a public audience in an accessible and engaging way. Packham’s involvement underscores the importance of accurate representation when visualizing the scale of the solar system and our place within it.
Public Unveiling and Community Engagement
“Ujuālnān (Grand Sky)” was officially unveiled on Monday, October 27, at 10 a.m. With a ceremony hosted by the Department of Arts & Culture in Pearsall Park. The event featured remarks from both Garza, and Dr. Packham. The sculpture is intended to be a lasting contribution to the city’s public art landscape, encouraging ongoing dialogue about our connection to the universe.
The project represents a significant investment in public art and community engagement, offering a unique educational and artistic experience for San Antonio residents and visitors alike. Glasstire reported on the unveiling and the artistic vision behind the installation.
Looking ahead, the City of San Antonio anticipates that “Ujuālnān (Grand Sky)” will turn into a landmark destination, fostering a deeper appreciation for both art and the wonders of the cosmos. Further community programming and educational initiatives are planned to complement the sculpture, ensuring its continued relevance and impact for years to come.
