New Mexico Museum of Space History indexed “Clyde Tombaugh biography” in connection with the public record around Clyde Tombaugh UFO sighting, a 1949 UFO/UAP dossier centered on Las Cruces, New Mexico, United States. The source is useful because it fixes a checkable part of the record: who published the material, what topic it addressed, and how it connects to the timeline, witness layer, official response or later research around the case.
The accessible source text states: Discovered the dwarf planet Pluto, hundreds of variable stars and asteroids, and two comets. In the archive context, that material is treated as a primary or secondary record to be compared with the case chronology rather than as a standalone proof of an extraordinary origin.
Additional context from the source adds: Clyde William Tombaugh was born in Streator, Illinois on February 4, 1906. He grew up on the family farm there until 1922 when the Tombaughs moved to a farm northwest of Burdett, Kansas. Those details matter only when they can be aligned with the case's date, location, named institutions, reported evidence types and possible conventional explanations.
The evidence boundary remains important. A source page can document that a report, document, video or database entry exists, but it does not by itself establish that the object or event was anomalous. This local record preserves the source's role in the case while keeping unresolved claims separate from confirmed facts. Original source URL: https://www.nmspacemuseum.org/inductee/clyde-w-tombaugh/
