Those of us in the western U.S. who enjoy vast open spaces may also be more likely to report UFO sightings, a new study suggests.

An analysis of unidentified aerial phenomena (UAP) reports (UAP is a new umbrella term that includes UFOs not just in the sky but also in space and underwater) suggests local environmental factors play a role in the number of UAP sightings reported.

The study, based on about 98,000 reports over 20 years as cataloged in an open-source, online dataset maintained by the National UFO Research Center (NUFORC), modeled how reported UAP sightings coincide with environmental variables such as light pollution and cloud cover, as well as things like proximity to airports and military installations. The results reveal the majority of reported sightings originate in the western U.S., along with a smaller hotspot in the northeastern U.S.

"It was completely unexpected," Richard Medina, a geographer at the University of Utah who led the study, told Space.com. "It's difficult to explain why we have this many more sightings in the West."
