We curate publications, articles, and key texts that inform the serious study of anomalous phenomena. The selection below highlights what we consider essential reading for scholars, researchers, and the curious.


Publications

  • The Visible College — 2025

    "Down the UAP Rabbit Hole"

    Tania Searle — The Visible College, March 2025

    An account of how academically trained members of The Visible College have engaged with anomalous phenomena — documenting the journey from skepticism to serious investigation, the experience of ontological disruption, and the value of scholarly community.

  • Journal of Astronomical Instrumentation — 2023

    "The Scientific Investigation of Unidentified Aerial Phenomena (UAP) Using Multimodal Ground-Based Observatories"

    Watters, Knuth, et al. — Journal of Astronomical Instrumentation, Vol. 12, No. 1 (2023)

    A major peer-reviewed paper co-authored by 38 researchers arguing for systematic, instrumented scientific investigation of UAP. Notes that "UAP have resisted explanation and received little formal scientific attention for 75 years."

  • Humanities and Social Sciences Communications (Nature) — 2023

    "Faculty perceptions of unidentified aerial phenomena"

    Yingling, Yingling & Bell — Humanities and Social Sciences Communications (Nature Portfolio), Vol. 10 (2023)

    A peer-reviewed survey of 1,460 tenured and tenure-track faculty across 14 disciplines at 144 major U.S. research universities, examining how they evaluate, explain, and respond to UAP. 19% reported that they or someone they know had witnessed UAP; 37% expressed interest in conducting research on the subject.

  • Progress in Aerospace Sciences — 2022

    "Improved instrumental techniques, including isotopic analysis, applicable to the characterization of unusual materials with potential relevance to aerospace forensics"

    Nolan, Vallée, Jiang & Lemke — Progress in Aerospace Sciences, Vol. 128 (2022)

    A detailed materials and isotopic analysis of physical samples associated with two reported UAP incidents — Ubatuba, Brazil (1957) and Council Bluffs, Iowa (1977) — co-authored by Stanford pathologist Garry Nolan and computer scientist Jacques Vallée. One of the few peer-reviewed studies of alleged UAP-related physical evidence.

  • Scientific Reports (Nature) — 2021

    "Exploring nine simultaneously occurring transients on April 12th 1950"

    Villarroel et al. — Scientific Reports, Vol. 11, Article 12794 (2021)

    A peer-reviewed study of nine point sources of light that appeared simultaneously on a single Palomar Sky Survey photographic plate from April 12, 1950, with no counterparts on plates taken minutes before or after. The authors examine and weigh competing explanations, including the possibility that the transients may be reflections from objects in near-Earth orbit.

  • The Astronomical Journal — 2020

    "The Vanishing and Appearing Sources during a Century of Observations Project. I. USNO Objects Missing in Modern Sky Surveys and Follow-up Observations of a 'Missing Star'"

    Villarroel et al. — The Astronomical Journal, Vol. 159, Article 8 (2020)

    The first publication of the VASCO project, which compares historical sky-survey catalogs against modern surveys to identify sources that appear to have vanished. The authors search 600 million USNO B1.0 objects against Pan-STARRS DR1 to identify candidates for further astrophysical investigation.
