Yahoo Laser to Ask: Anybody there?

Mexico’s Teotihuacan, once the center of a sprawling pre-Hispanic empire, is set to become the launch pad for an attempt to communicate with extraterrestrial life. Starting Tuesday, enthusiasts from around the world have a chance to submit text, images, video and sounds that reflect human nature to be included in the message. Those contributions — part of media company Yahoo’s Time Capsule project — will be digitalised and beamed with a laser into space 25 October from the Pyramid of the Sun at Teotihuacan, now an archeological site near Mexico City
