UFOLOGY Glossary Series - E
A series to help people new to the topic understand the terms, concepts, and language used in the study of UFOs and alien phenomena.
The world of ufology is vast, mysterious, and often overwhelming for newcomers and seasoned researchers alike. With decades of reports, theories, terminology, and classifications, understanding the language of UFO research is essential for making sense of the phenomena.
This Ufology Glossary is designed to be a living, evolving reference guide for anyone interested in the study of unidentified flying objects, alien encounters, and the deeper mysteries of our universe. Whether you're exploring government disclosures, diving into abduction accounts, or just trying to decipher terms like “CE-5” or “anti-gravity propulsion,” this glossary is your companion through the strange and fascinating world of UFO phenomena.
Each entry is organized alphabetically and includes clear, concise definitions to help demystify the language used by researchers, experiencers, and theorists across the field.
We begin with the letter A, and from there, the glossary will continue to grow—entry by entry, mystery by mystery.
EBE (Extraterrestrial Biological Entity)
A term often used in government or military contexts to describe non-human lifeforms believed to originate from beyond Earth.
Electromagnetic Interference (UFO Encounters)
The disruption of electronic devices such as radios, car engines, or aircraft systems during UFO sightings, often cited as evidence of the craft’s unusual energy output.
Entity (Extraterrestrial)
A general term for non-human beings encountered during UFO sightings, abductions, or telepathic contact. Entities may be physical, energy-based, or interdimensional.
Experimental Aircraft (Misidentified UFOs)
Secretive or advanced aircraft developed by military programs that are sometimes mistaken for UFOs due to unusual shapes or flight capabilities.
Extraterrestrial
Any lifeform originating outside of Earth. In ufology, it typically refers to intelligent beings capable of space travel and contact with humans.
Extraterrestrial Contact
Any form of communication or interaction between humans and alien beings, including visual sightings, telepathic messages, abductions, or diplomatic-style exchanges.
Extraterrestrial Craft
A vehicle or object believed to be manufactured and operated by alien beings. These are often described as discs, triangles, spheres, or cigar-shaped.
Extraterrestrial Hypothesis (ETH)
The theory that UFOs are best explained as physical spacecraft piloted by intelligent life from other planets or star systems.
Exoarchaeology
The speculative study of alien artifacts or ruins, especially in relation to ancient Earth civilizations or suspected extraterrestrial contact in the distant past.
Exobiology
The scientific study of possible life beyond Earth, including its origins, evolution, and potential habitats, often used to support theories related to alien life.
Exopolitics
The field of thought that explores the political implications of extraterrestrial contact, including alleged treaties, secrecy, and interstellar diplomacy.
Eyeshine (Entity Encounters)
A reflective glow reported in the eyes of alien beings during nighttime encounters, often linked to their biology or the light emitted by their craft.
Energy Beings
Non-corporeal entities described in some contact or abduction cases, often composed of light or energy and lacking physical form as we understand it.
Environmental Anomalies (UFO Landings)
Unusual physical changes to the landscape—such as scorched ground, radiation, or plant mutations—allegedly caused by UFOs during landings or close encounters.
