A strange light over the Australian capital – a ball of light that lit up Canberra’s skies before rapidly disappearing.

During the recorded incident, the sky was illuminated by lightning as well as a green-red hue, and then a white orb shone bright in the dark sky and faded away after a few seconds.

Astronomer Dr. Brad Tucker of Australian National University debunked the UFO claims, saying it was an equally mysterious phenomenon known as ball lightning.

According to Dr. Tucker, the green and red light faintly glowing in the background could be mistaken for an aurora, where the sun’s energy hits the atmosphere, rubbing it with friction and charging the gas.

"But the problem is there was no activity from the sun, it was cloudy, we can't see the aurora, so it doesn't really fit,” he explained.
