When a team of underwater explorers
discovered a mysterious man-made object 91 metres under the Baltic Sea
in Europe, they were stumped as to what it could be.
Dubbed the 'Baltic Sea Anomaly', the structure has been likened to an alien spaceship due to its round shape and futuristic looking lines.

Professional diver Stefan Hogerborn said in a bizarre twist, electronic equipment would fail when the crew passed over the unidentified object.
“Anything electric out there, and the satellite phone as well, stopped working when we were above the object,” Mr Hogerborn said.

The huge object measures 61 metres wide and eight metres tall, prompting many to draw their own conclusions as to what it could be.
Some have speculated that it could be a sunken Russian ship. Others have said a battleship gun turret or a Nazi anti-submarine device.
Of course, paranormal enthusiasts whole-heartedly believe it is an alien craft.

He found the materials collected in the samples were "metals which nature could not reproduce itself".
The crew need to raise $360,000 before they can set out on their next expedition to the anomaly.
