If aliens are among us, they apparently have a taste for warmer climates.
A video has been released purporting to show an unidentified craft flying directly into a volcano in Mexico.
The clip, recorded on 30 May near to the Popocatepetl volcano, features a white light which approaches the mountain, slows down, circles and then 'enters' the smoking crater.
Broadcast by FOROtv in Mexico, the clip has since become an internet sensation.
