17. Kolkata Shape-shifter
On October 29, 2007, a rapidly moving object was seen in the eastern horizon of Kolkata, India. It was initially shaped like a ball, and was captured on a camcorder in the early hours of the morning. It later transformed shape, forming a triangle, and later on, a line. It was spotted by hundreds of people, describing it as having bright, multi-colored lights in the shape of a halo.
