An ocean explorer team, led by Swedish researchers, has found a strange UFO-like object deep on the floor of the Baltic Sea.

The object was found very close to a flying saucer- like object that was found by the researchers back in July, 2011.

The expedition, led by Peter Lindberg, started when the team, who had successfully recovered objects from sunken ships, announced that they had come across a strange round object around 300 feet on the ocean floor in the Gulf of Bothnia, between Finland and Sweden. Pictures taken from the expedition showed what appeared like skid marks, suggesting that the object may have moved across the ocean floor.

It was this placement of the object that proved to be more intriguing than the object itself. The scars suggested that the object left a trail from where it crashed to where it ultimately laid on the ocean floor.

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 told local media. Lindberg claims to have spent hundreds of hours watching sonar images of the seafloor and this find is a first for him.

There was much speculations and debates at that time regarding the identification of the object owing to the low resolution of the photos taken. Some believed that it was an unidentified flying object (UFO) or an extraterrestrial visit from possible aliens in a flying saucer while others suggested that the object is the Millennium Falcon starship from the Star Wars series. Other speculations regarding the object included Russian warships, a marine version of a Stonehenge or an opening to another world inside the Earth.

However, although the object has remained unidentified till date, the story seemed to get more intriguing after reports indicated the presence of a second smaller, disc-shaped object close to the first object.

The CNN reported that the original mysterious object is not on its own down there. The ocean explorer team also found another, smaller, disc-shaped object nearby. Both show a rigid tail or drag marks more than 400 meters (about 437 yards) long. Their size and distinctive shape are generating some peculiar theories.

However, unlike the first object whose shape was well-defined, the second closely resembles a lumpy eggplant or a blueberry muffin sprouting what looks like an owl's head.
