MESMERISING footage has emerged showing a mysterious UFO hovering in the sky and appearing to change shape.

Amateur video shot by a member of the public in Houston, Texas, shows the unidentified object glistening as it travels through the sky.

The UFO appears as no more than a bright speck against the blue background of the clear sky.

But when zoomed in, stills from the footage show the shiny object appears to change shape as it moves.

It morphs from fat to skinny as it glides along before disappearing behind a building.

The cameraman is able to follow it for several minutes before the mysterious object vanished for good.

The stunned witness described what they saw in a statement quoted on UFO spotting website the Mutual UFO Network (MUFON).

They claimed they had just stepped out of a car at 3.15pm on November 23 when the object first appeared.

The witness said: “I noticed the reflection of light in the sky. It was stationary, and appeared to change shape.

“After about 30 to 45 seconds, the object began moving very slowly, to the east-southeast.

“It made no sound, or was too far away to distinguish sound. Elevation did not appear to change.”

The witness said they eventually lost the UFO but were able to film it for just over four minutes.

Texas MUFON State Section Director Charles Stansburge is investigating.

Some stills of the object look eerily similar to another UFO which was spotted above Bursa in north-western Turkey earlier this year.

The shimmering shape was similarly seen gliding along in broad daylight, glittering in the sunshine in the middle of the day.

And the cameramen were also able to film it for several minutes before losing it behind trees and houses.

After the footage was posted online, some web users, spotting that the object was bent in two places resembling a surfer on a board, compared it to comic superhero the Silver Surfer.
