Crop Circles

Crop circles have been observed since many years in the crop fields across the world. They are patterns created by the flattening of crops. Recently a mysterious formation was spotted, an intricate pattern measuring approximately 60 ft in diameter near Avebury in Wiltshire, UK. It was made up of two segments of arc of decreasing size between the concentric inner circles.

There have been given many explanations for the formations of crop circles. They have been called man-made or geological anomalies while they are also said to have been made by extra terrestrial life forms.

Early examples of crop circles have been simple circles, but later on, the designs got complex with intricate details, including geometrical designs and three dimensional structures. The shapes include a bee, a rectangle, a ring and even a three dimensional formation.

The mystery of how crop circles are created has still not been solved. There are evidences suggesting that the some of the crop circles were man-made. Cynics have claimed that the patterns are the work of human pranksters. But crop circle enthusiasts argue that there are not enough hours of darkness to be made by humans.
