Did Aliens Crash in the Baltic Sea?

Finally, a real reason to send conspiracy theory extremists to the bottom of the sea: A team of Swedish treasure hunters have uncovered what they think could be a UFO crash site in the Baltic Sea, reports Gizmodo. The 60-foot disc sits at the end of what appears to be 985-foot-long impact tracks in the Botnia Gulf between Sweden and Finland.

The team made the find some 285 feet underwater on June 19 using sonar equipment. "You see a lot of weird stuff in this job," says the team commander. "But during my 18 years as a professional, I have never seen anything like this. The shape is completely round… a circle." The team doesn't claim the object is an alien craft, but they're not sure it's a natural structure. The commander says it could be "a new Stonehenge." (More UFO stories.)
