A strange circular shape seen on Google’s satellite maps has created a stir among ufologists online, who are speculating that it could be a hidden submersible off the coast of Greece. The circular object was brought to people’s attention by the website Disclose.TV, which posts information about UFOs and aliens. According to the niche publication, the unidentified submersible object was viewed online using Google Maps in the Aegean Sea.
RIJEKA, Croatia — You've heard about crop circles, but what about seagrass circles? Aerial photos of the coastline of several islands in Croatia show regular circles of sand amidst a sea of Posidonia oceanica, a seagrass endemic to the Mediterranean. Biologist Mosor Prvan from the Sunce Association, a nonprofit environmental organization that first noticed the circles, doesn't have an explanation for the phenomenon. The circles are about 164 feet in diameter and are roughly at the same distance from the islands and from one another
If you know where to look, the circles are easy to spot on Google Maps. But Prvan and the team from Sunce have dived in these locations to check with their own eyes. "At first we thought it was some sort of photo manipulation, so we dived at one of the locations, and sure enough, the circles were there. They had a perfect edge, as if someone pulled the Posidonia out with a corkscrew," says Prvan.
