Given that a ‘UFO’ is any object in the sky that can’t readily be identified, then this is most definitely a picture of a UFO.

Whether this represents the first hard evidence of visitors from a distant world or not is a whole other question.

Bristol mum Fiona Powell took a scenic photo on a family walk along Severn Beach.

It was only when she looked at the image later that she noticed what appears to be an indistinct black disc-shaped object in the upper right-hand corner.

Fiona, who took the photo on Tuesday, February 9, said: “I’m undecided whether I believe in Aliens or not, but this photo certainly meets the criteria of a UFO.

"After I had taken the photo, my friend zoomed in and it looked even more like a UFO. I have shown the photo to a few sensible friends and they all think it is incredible."
