01 Definition

Astronomical research initiative comparing historical pre-satellite photographic plates with modern sky surveys to detect disappearing stars and technosignatures.

02 Detailed_Analysis

The Vanishing and Appearing Sources during a Century of Observations (VASCO) project, directed by Dr. Beatriz Villarroel (Stockholm University / Nordita), cross-references photographic plates from the 1950s US Naval Observatory survey (USNO B1.0) with modern digital surveys like Pan-STARRS. Because the 1950s plates predate artificial orbital launches, unexplained point sources appearing on a single epoch that vanish completely are analyzed as potential non-terrestrial technosignatures, high-albedo artificial satellites, or rare astrophysical transients.

03 Key_Facts

  • Founded and led by astrophysicist Dr. Beatriz Villarroel in 2017.
  • Compares 1950s pre-Sputnik photographic plates with modern digital all-sky surveys.
  • Identified over 100 single-epoch vanishing point-source candidates.
  • Investigates anomalies as astrophysical transients, artifacts, or technosignatures.

Overview

ASSESSMENT: Beatriz Villarroel (astronomer, Stockholm University / Nordita) runs the VASCO (Vanishing and Appearing Sources during a Century of Observations) project — the ASTRONOMICAL SEARCH FOR TECHNOSIGNATURES. Started 2017. Compares 1950s photographic plates (USNO B1.0, ~600M objects) with modern surveys (Pan-STARRS). 1950s plates taken BEFORE Sputnik (no satellite glints). KEY FINDINGS: ~150,000 preliminary candidates, ~24,000 visually examined, ~100 single-epoch point sources. 'Thousands of objects visible in 1950s that no longer seen today.' 'Short-lived transients' — bright for minutes, then vanish. 2021: 9 TRANSIENTS APPEAR AND VANISH WITHIN 50 MINUTES in confined sky portion. 'Several groups of multiple transients' 'eluding conventional explanation.' NO Dyson spheres or failed supernovae (< 1 in 600M in 70 years). HYPOTHESES: radioactive isotopes from atomic tests, plate defects, M-dwarf flares, high-z supernovae, sub-second optical flashes. 2025 paper: 'groups of short-lived transients on historical photographic plates that lack conventional explanation.' Villarroel counters 'emulsion flaws' — sub-second flashes naturally appear sharper/circularer. Sol 2024 speaker. CRITICAL: Pre-Sputnik 1950s transients = NOT satellites. 9 transients in 50 minutes = coordinated pattern. 'Technosignatures' framing = SETI via sky survey. Connects to Vallée's control system (phenomenon present throughout history).

Entity Type: AssessmentBeatriz Villarroel (VASCO Project, Thousands of Unexplained Transients, Technosignatures) is an analytical assessment synthesizing multiple data points.
