Scientists have made a remarkable discovery of a sphere that some believe to be an unidentified flying object (UFO).

The sphere, according to social media page @Truthpolex, was spotted March 2 flying over the town of Buga, Colombia, before it landed. Jose Luis Velazquez, one of the researchers studying the three-layered sphere, noted that it shows “no welds or joints,” characteristics normally indicative of human manufacture, which further bolstered his belief in its extraterrestrial origin.

Julia Mossbridge, the executive director of the Institute for Love and Time (TILT), and a member of the University of San Diego Department of Physics and Biophysics, told Fox News Digital she remains skeptical of its extraterrestrial origins.

“It looks to me like a really cool art project,” she said, urging caution in drawing immediate conclusions.

Mossbridge urged thorough vetting before declaring anomalies in mysterious discoveries.

“Before you decide something’s anomalous or a UFO, bring the object to a group like the Galileo Project,” she said. 

She said experts can determine if the material is “clearly non-human-made.” 

Despite her misgivings about the discovery in Buga, she said it doesn’t “discount all the other objects that are of extraterrestrial origin.”
