UFO in New York? Explanation for the Light in the Sky

A mysterious white light appeared in the sky over the U.S. East Coast on August 12, sparking UFO speculation.

Despite conspiracy theories, the explanation was simpler: the launch of the United Launch Alliance's Vulcan Centaur rocket from Cape Canaveral, Florida.

The rocket carried an experimental navigation satellite for the U.S. military, the first in 48 years, according to space.com. The satellite will test new technologies and provide data similar to a GPS system.
