The extraterrestrial was spotted in the Yakutia region in Russia's Siberia province and a man called Semyon, who filmed the alien footage, said it was floating above houses and had a vapour trail.

One theory suggest the lights could have been caused by lasers and a drone.

The Siberian Times say police have not had calls about this strange sighting.
