Chicago man captures UFO resembling alien face from his balcony

Dietrich Zeigler, a Chicago-based photographer, has shared an amazing snapshot of an eerie UFO (unidentified flying object) that was changing colours in the night sky while it remained motionless.

Official Pentagon records have informed us that UFOs are typically round, triangular, or even a white oblong resembling a "Tic Tac."

The US government can now include a brand-new shape on its list that is unlike anything we have ever seen.

It might look like a mask, an extraterrestrial face, a native totem, or even Rafiki the monkey from "The Lion King", depending on who is looking at it.

Experts described the image as "spectacular" and "beautiful," but they are at a loss as to what it could be.

Chicago-based photographer Dietrich Zeigler captured the amazing image, which he only shared with MailOnline.

"It was around evening just as the sun dipped below the horizon," he said.

"I noticed some colorful shimmering and took out my 70-200 MM lens and shot this."

"The object's appearance was striking, with a palette of purple, gold and green."

"It seemed to be changing colours, but the shape remained the same which looks like a mask."

"After quickly heading indoors to examine the photos, I was unable to locate it in the sky again."

Zeigler said it "seemed as stationary as a star to the naked eye, although slight differences in the photos he took suggested it might have been moving slightly."

"I was quite startled upon reviewing the photos on a larger screen," he added.
