The bizarre sight was found by renowned conspiracist Tyler Glockner yesterday (February 23).
In a video posted to his YouTube channel secureteam10, Tyler uses the Google software to scroll around the Earth.
A straight line can be seen spanning the planet from the tip of Antarctica to the North Pole.
The distance it covers, as Tyler points out, is between 12,000-13,000 miles.
“This was not created by an airliner,” he said.
“This map here and at this distance only gives us images of the major cloud formations and weather around the Earth.
“There are obviously hundreds of thousands of contrails by planes but we cannot see them.
“Whatever created this cloud formation, if that’s what it is, would have to be massive.
“Not only that, it would have the ability to go from Antarctica spanning 13,000 miles in a straight line all the way to the North Pole without stopping and without changing direction.
“It would have to do this fast enough to leave this entire line of clouds in perfect condition like it moved over the Earth in a matter of minutes.”
More than 360,000 people have seen the baffling clip, with many offering their own thoughts.
“That has to be proof of an alien mothership, surely?” one asked.
But many others pointed out that Google Earth is a computer-generated image of our planet – meaning the sight is unlikely to actually be seen from space.
“Might be photo stitching – multiple photos being stitched together without editing where the photos to not perfectly match,” another suggested.
