A mysterious circle on a grainy scan, this is what scientists are claiming is finally evidence that Earth has been visited by aliens.
Researchers have claimed the fuzzy outline is a flying saucer that ended up 300ft down on the ocean floor between Sweden and Finland.
They were stunned when sonar scans taken while searching for a century-old wreck showed up the shape against the dirt.
The ocean exploration team which found it claims that the earth around the craft has been scarred, suggesting it has tried to move around.
Lead researcher Peter Lindberg also suggested that another explanation could be that it was ‘a new Stonehenge’.
