The mystery diamond-shaped object pulsated, getting brighter and bigger and then fading only to reappear again.
It was spotted over the sky in Merseyside at around 4.45am today.
Matthew Oliver, who filmed the curious phenomenon, said: "It caught my eye as it was shining very brightly through my bedroom window and as I watched it began to gradually dim then slowly increase again in intensity as if on a dimmer switch.
"It was also incredibly large in size a lot larger than any star i have ever seen.
"I grabbed my camera and went upstairs into my office and began filming out of my attic window.
"Much to my surprise as I zoomed in on the unknown object i noticed that it wasn't circular at all, but diamond shaped and it seemed to be pulsating in the center.
In the video a woman in the background exclaims: "It's not a star. Or at least I don't think it is.
"It's the strangest star I've ever seen."

UFO filmed by a highly sensitive camera. Astronomical Observatory.
In reality, the apparent size of the object was and glow like the lunar disk.
To say exactly whether it was a UFO in the atmosphere, or it was falling and burning in the upper layers of the space object is difficult.
The camera includes a lens "Fish-eye" for the review of 360 degrees. Because it is in the center of the field of view of the image is stretched and it seems longer.
