June 21–Jan. 6, 2019, the Smithsonian American Art Museum in Washington, D.C., presented “Trevor Paglen: Sites Unseen.” Working at the crossroads of art, science, and geography, Trevor Paglen’s photographic and image-based projects prompt viewers to confront systems and objects that are typically hidden from public view.
His work probes questions of surveillance, secrecy, and privacy through carefully composed photographs, long exposures, and investigative methods that reveal infrastructures and operations designed to be unseen. One notable example is the 2010 chromogenic print “STSS-1 and Two Unidentified Spacecraft over Carson City (Space Tracking and Surveillance System, USA 205),” which captures objects in orbit that most people never notice and invites reflection on who controls what we can observe.
Paglen’s background combines rigorous academic study with artistic practice: he holds a BA from the University of California, Berkeley, an MFA from the School of the Art Institute of Chicago, and a Ph.D. in geography from UC Berkeley. This blend of disciplines informs his approach, which often merges field research, data analysis, and photographic techniques to document hidden networks—satellite systems, classification sites, covert facilities, and other elements of the contemporary surveillance landscape.
The exhibition “Sites Unseen” gathers images and projects that make visible the infrastructures and apparatuses underpinning modern surveillance and secrecy. Viewers encounter large-scale photographs, long-duration exposures of the night sky, and investigation-based works that translate complex technical systems into compelling visual narratives. Rather than offering straightforward explanations, the pieces encourage curiosity and critical thinking about power, visibility, and the ways technology shapes public and private life.
Paglen’s images often balance aesthetic beauty with unsettling subject matter: they can be visually striking—rich in light, composition, and scale—while simultaneously revealing the existence of systems intended to operate beyond public scrutiny. This tension between form and content is central to his practice, inviting audiences to appreciate the photos on their visual merits while also considering the ethical and political implications behind what they depict.
By combining artistic sensibility with investigative rigor, Paglen’s work challenges viewers to consider the limits of perception and the consequences of living in a world increasingly mediated by unseen infrastructures. Whether through photographs of satellites streaking across the sky, portraits of sites associated with covert operations, or conceptual projects that expose the language and methods of classification, “Sites Unseen” offers a sustained exploration of secrecy, technology, and the politics of visibility.
The exhibition at the Smithsonian American Art Museum provided an opportunity to engage with these themes in a public setting, encouraging visitors to think about surveillance not just as an abstract concept but as a tangible presence shaped by institutions, technologies, and decisions. Paglen’s combination of art, science, and geography creates a distinctive visual vocabulary for understanding contemporary systems of observation and control—making the invisible appear, and asking viewers what they will do with that knowledge.
