A mysterious square shaped UFO with flashing lights was spotted hovering over the night sky of Tyneside by a dog walker. Since then many people in the locality have come up to report the same sighting over the England town.

Craig Lowther spotted a mysterious flying object with pulsating light in the sky while he was out to let his dog for a walk.

"I always look up at the night sky when I go out because where I live you get a great view of the stars. But when I looked up I noticed what I thought was a plane travelling on an unusual flight path," the venture capitalist told Chronicle Live.

He immediately got his camcorder to record the strange purple coloured object and described the movement as unusual compared to that of a flight.

"It was an unusual colour for a plane and it was not moving as you would expect a plane to move," he added.

"I used the zoom so I could get a better look, and what I saw surprised me. It appeared to be a dome with a bulge in the middle and it had pulsating lights on it. I am out at night a lot walking the dog but this was like nothing I have ever seen before."

However, experts believe that a bright star has been mistaken for a flying object.

"The brightest star in the night sky is called Sirius and it is often mistaken for a UFO because of how bright it is and how low in the sky it is," Alex O'Neil, an Astrophysics student told the website.

O'Neil also said that the pulsating light is just a trick of the eye.

"It appears to be twinkling or pulsating because when light passes through the atmosphere, it becomes distorted. Viewing Sirius through a telescope can be very confusing because it appears to move and change colour. It is all just a trick of the eye."

What is your view about the mysterious flying object? Is it just a star very close to Earth or a UFO?
