Swedish treasure hunters discovered a mysterious object on the bottom of the sea floor that resembles a crashed UFO.
The Ocean Explorer team on June 19 marveled at the baffling discovery of a 60-foot-wide disc found lying in the mud at the bottom of the Gulf of Bothnia, which is between Finland and Sweden, some 285 feet below the surface of the Baltic Sea.
The team, led by researcher Peter Lindberg, found that there were impact tracks extending away from the object for almost 1000 feet.
The hunters stumbled up on the UFO-like object while hunting for an old shipwreck they believe contains expensive antique champagne.
"You see a lot of weird stuff in this job, but during my 18 years as a professional I have never seen anything like this. The shape is completely round," Lindberg said in reports to local media.
Ocean Explorer released blurry sonar images showing the circular object with marks that looks as if it landed with a skid. Since then, there have been speculations that it could be a crashed flying saucer.
But Lindberg didn't suggest that it was a flyer saucer that skid-landed.
According to Discovery News, there another theory: the unidentified sunken object is neither an extraterrestrial craft nor a natural feature but instead a rotating gun turret from a World War II era battleship.
Discovery News reported that it is possible that an explosion on the ship's deck could have blown it out of the deck ring where it anchored and it slid into the ocean's depths, intact.
But such an explosion would not necessarily have sunk the ship, and so the lack of nearby wreckage may not be a mystery, according to the Discovery News report.
But whatever the object is that has garnered much speculation, it seems Lindberg and his team doesn't care too much to find out.
"It is not in our sphere of interest to go for this object since the cost for each hour out on the sea are tremendous ... since it might be nothing," Lindberg said. "It's up to the rest of the world to decide what it is."
