Disambiguation

In the context of UAP investigations, celestial phenomena serve as a baseline category of 'known natural phenomena' used to explain apparent misidentifications.

Concept

Naturally occurring, observable events in the sky and cosmos—including eclipses, meteor showers, comets, planetary alignments, auroras, and stellar explosions—governed by the laws of physics and studied by astronomy.

Eventos naturais observáveis no céu e no cosmos—incluindo eclipses, chuvas de meteoros, cometas, alinhamentos planetários, auroras e explosões estelares—governados pelas leis da física e estudados pela astronomia.

  • Astronomical events include eclipses, supernovae, novae, impact events, transits, occultations, gamma-ray bursts, and gravitational-wave events
  • Celestial body events are studied by the scientific discipline of astronomy
• What is an Astronomical Phenomenon?
  Philip Metzger (NASA scientist)▎ high· 2026-05-14
  • Astronomical phenomena are visible events in space involving light, motion, shadows, or changes in appearance
  • Examples include solar/lunar eclipses, meteor showers, planetary alignments, comets, auroras, transits, supermoons, and star conjunctions
  • These phenomena follow scientific laws and are predictable and studyable
• Unidentified Anomalous Phenomena (UAP)
  NASA Science▎ high· 2026-05-14
  • UAP are defined as observations of events in the sky that cannot be identified as aircraft or known natural phenomena
  • This definition implicitly excludes celestial phenomena from UAP classification
  • Distinguishing genuine UAPs requires ruling out known celestial objects and phenomena
