Paul and Sylvia Mayo were leaving a gas station in Darwin, the capital city of Australia's Northern Territory, in the early morning hours of June 12, 2015, when their car dash cam caught something streaking through the air.

"My wife and I both saw the object shoot across the sky, and the next day we looked at the video footage from our dash cam to see if it had recorded the object and were delighted to see that it had," Paul Mayo told The Huffington Post in an email.

"We were puzzled at the time to explain what it was, but being the busy people we are, put it aside and didn't think that much more about it, particularly since we're both UFO skeptics."

Mayo explained how, six months later, he watched the video footage again, still puzzled by it all.

"Being lifelong amateur astronomers and astrophotographers, we know what a shooting star looks like, what an aircraft looks like, how fast an aircraft moves, what a satellite looks like, what the International Space Station looks like, but the object on our footage didn't fit any of these airborne objects."
