    According to reports from Russia's NTV television channel, the circles are connected by straight lines.

    Similar patterns have been found in different locations across the world, and their origin is still the subject of intense speculation.

    The extraterrestrial version of the story has not been ruled out, though the most earthly theory suggests the circles are a result of bio-energetic charges emanating from the planet.
