Popular UFO hunter Scott C Waring posted on his blog that an alien space ship was trying to camouflage itself in the clouds.
The photo shows faint clouds with a rainbow light scattered through the atmosphere.
However, conspiracy theorists are pointing to a large, circular but translucent object in the clouds which they believe is a UFO using a cloaking device.
Mr Waring says of the image, which was taken in General Santos, Philippines: “This awesome UFO was hiding above a cloud during sunset and for a few minutes the cloaked craft was visible to the naked eye.
“Such beautiful colours and notice the round disk edge of the craft. This looks to be at least 500 meters across.”
The anonymous person who took the image and passed it onto the UFO hunter said: “Unfortunately, I had only one phone at hand, the ‘good’ HD Camera is currently defective. The colours were actually much more intense.”
However, other self-proclaimed experts believe this is not concrete proof that humanity is looking for in the search for extraterrestrials.
Nigel Watson, creator of the UFO Investigations Handbook, said the light is simply a trick of they eye.
He said: “Spectacular footage of a sundown, giving a halo impact that may be interpreted as a flying saucer – properly by Scott Waring anyway!
“I do not see the place he will get the estimated measurement of the ‘object’ as 500 metres throughout, with out understanding the gap and measurement of the the cloud.
“Anyway it appears to be like good however tin foil hats can go on standby in the intervening time.”
The most likely explanation would be apophenia – where the brain recognises specific patterns in things.
If someone has hinted something looks like a UFO for example, the brain will try to picture it in that way.
