The incident was filmed on December 1 in Arizona, USA, and has triggered speculation online
A video showing a UFO bursting through clouds and appearing to shoot a bolt of lightning into the ground has gone viral online.
The video was reportedly published by a Spanish Facebook group but has triggered specualtion online of life from other planets.
It shows a stream of blue-coloured light above some clouds and an object that appears to be hanging from the heavens.
Scott Waring from the UFO Sightings Daily website says the incident occurred on December 1 in Arizona, USA.
He appears to believe the video is real.
“Arizona is a famous hotspot for UFOs and Alien bases, so its nice to get this substantial evidence of their existence in that area,” he wrote.
“This is an alien ship, shooting off through the clouds, leaving earth.
“It almost looks like a meteorite, but it’s not falling, it’s going up.”
There are suggestions online the light was from some sort of lightening or other weather-related event.
The were also suggestions it could also be a hoax.
