Mystery surrounds the appearance of a turquoise, light shaped UFO which appeared in the sky over Holland.
Nature blogger Harry Perton was taking pictures of the clouds when he was left stunned when he appeared to capture the UFO on camera.
He had been snapping pictures of a storm in Groningen, Holland to upload to his blog last week.
But when he checked his camera to review some of the pictures that he had taken, he spotted the the jellyfish-like UFO floating in the night sky emitting an eerie flash of green light.
Mr Perton said: ‘I saw from my window hauntingly beautiful skies and I waited for the rain to subside before I went out.
‘I was taking photos and suddenly something flashed. At first I thought it must have been my camera but the flash was not up and there was not a drop on my lens.
‘I decided it must have been a strike of lightning – but back at home I saw something strange in one of the photos that I took – what looked like a UFO.’
And since the image was posted online, it has sparked a flurry of online debate about what it could be.
But despite some speculating it could be an alien object, Mr Perton is certain there is a plausible explanation.
He added: ‘Personally though I am not a UFO believer – I think it was probably something meteorological.
‘Maybe a ray of the sun peeked through the storm cloud and created this effect.’
