We just got a picture of an object over the skies of Arizona and Mexico -- and some residents there are doubting the object is a giant research balloon, as NASA claims.
Calls came pouring in yesterday about the mysterious bubble floating stationary for around one hour. NASA says it's a 4,000-pound research balloon used to measure gamma ray emissions. NASA claims the balloon generally floats at 130,000 feet -- more than 3 times higher than the cruise altitude of a commercial jet.
Thanks to our friends at Ye Olde UFO Store for the pic.
