The Baltic Sea Anomaly is a geological feature on the floor of the Baltic Sea, currently unexplained by experts.
An unexplained observation, the Anomaly was originally discovered by a team named the Ocean X diving team.
Widely discredited so far, the formation seen at the bottom of the sea has been explained as a UFO.
Finland, Estonia and Russia border the Baltic Sea – but is it really home to a UFO?
What is the Baltic Sea Anomaly?
Discovered by the Swedish Ocean X team, the Baltic Sea Anomaly was found by sonar imaging of the sea floor.
The team, describing themselves as ‘treasure hunters’, were returning from an expedition to the sea floor when the discovery was made.
Searching an old sea wreck in the summer of 2011, the team found “blurry but interesting” imaging from the ocean floor.
Baltic Sea Anomaly explained: What is the Baltic Sea Anomaly?
The original images resembled a UFO, and included an oddly shaped and unnatural formation on the sea floor.
Images showed a crop of land some 60-metres (200 ft) in diameter.
The object resembles the famed Millennium Falcon, a space ship of Star Wars fame.
Images have shown what appear to resemble stairs, ramps and other structures which are not naturally reproduced.
The image of the Baltic Sea Anomaly
Ocean X team member and professional diver Stefan Hogerborn, released his account which suggests technology is subject to malfunction in the area surrounding the site.
Even on the surface, apparently the Ocean X teams’ cameras and satellite phones would not turn on, preventing the team from confirming the Baltic Sea Anomaly.
Talking to website Earth We Are One, Mr Hogerborn said: “Anything electric out there, and the satellite phone as well, stopped working when we were above the object.
“And then when we got away about 200 metres, it turned on again, and when we got back over the object it didn’t work.”
The location of the Baltic Sea Anomaly
Team member Dennis Asberg said: “I am one hundred percent convinced and confident that we have found something that is very, very, very unique.”
“Is it a meteorite or an asteroid? Or a volcano? Or a base from say, a U-boat from the Cold War which has manufactured and placed there? Or if it is a UFO?
“Well, honestly, it has to be something.”
According to fact checker Snopes.com, there is no evidence that the object at the bottom of the Baltic Sea is a a UFO, and we may never know what the Anomaly is.
