The extraordinary find was spotted by Blake and Brett Cousins – two brothers who share their UFO-based insights on their YouTube channel thirdphaseofmoon.
“Do you see what I’m seeing here?” Blake begins, scanning through the satellite imagery.
“It’s a straight line across Europe and Russia and that whole area.”
He continues: “Pretty much the whole Asian continent is covered up by this straight lines.”
The duo believe the trail could not have been left by a rocket or meteorite moving across the planet’s face, with Blake claiming “It almost looks manufactured”.
To add to the mystery, they even claim the sighting was “scrubbed” by the mapping software.
The pair then question whether or not the satellite image is actually real, but decide it most likely is not an elaborate hoax by Google Earth.
Blake then concludes: “This is one of the biggest trails that I have ever seen that basically could rip through a system of clouds.”
The Cousins brothers’ startling footage has gained more than 17,000 views since its upload on Thursday (November 27).
Some believe the strange line may have been created by a “camouflaged UFO” hovering over the planet.
One person wrote: “It looks like it could be a cloaked vehicle.”
Others claim the line may be a result of a “glitch in the matrix”.
But some sceptics believe the weird image “was probably Photoshopped by a joker at NASA or Google to get a debate going”.
