A strange light moving across the sky during the Christmas period has been the source of much debate since it was shared on social media.
Webcams in Mexico captured the eerie light moving erratically above the volcano of Popocatepetl, which lies in the eastern half of the Trans-Mexican volcanic belt in the centre of the country. Many social media users were quick to state that they believed it to be a UFO sighting.
Others even went as far as to say that the strange light was more proof that extra-terrestrial beings are monitoring our planet. But those less than convinced by the authenticity of the footage suggested that it was merely the flare of a firework – causing a debate to arise.
