Bill Stepp of NASA's Columbia Scientific Balloon Facility in Palestine, Texas, says the mysterious flying orb was a 4,000-pound NASA research balloon used to measure gamma ray emissions.
Stepp says the balloon usually floats at 130,000 feet and can be seen for about 170 miles on a clear day.
Jennifer McCoy, who runs a UFO-themed Store in Sedona with her husband, says it "looked like the gigantic bubble from the Wizard of Oz."
