Strange footage has captured a mysterious flying object cutting through the sky close to the mouth a volcano just days after it erupted.
Cameras spotted the white object, followed by streaks of smoke, flying behind Popocatepetl in Mexico, before passing out the other side.
The sighting, captured by a 24-hour webcam focused on the 18,000ft mountain every day since last week, has prompted UFO hunters to suggest that it could be a sign of extra terrestrial life.
it would be unusual for a plane to fly so close to such a dangerous site and conspiracy theorists often claim to make alleged UFO sightings at volcanoes.
They suggest aliens are studying Earth's geothermal activity so that they can understand how it works.
Another theory is that the bright lights could be volcanic material being ejected or an atmospheric phenomenon.
n a more radical suggestion, some scientists say the material from which these UFOs are formed could trigger hallucinations, which may explain bizarre first hand accounts of alien sightings.
After watching Popocatepetl's latest encounter, viewers have been split on whether or not UFOs are flying in our skies.
Angel Ramiro Rodriguez said: 'I do think there is life on other planets. We'd be very selfish to think we are the only ones in the immensity of the universe.'
