Contacting outer space

a pyramid in Mexico A unique experiment to try to communicate with life in outer space and give a picture of life on earth is to take place from a pyramid in Mexico. Thousands of people around the world have already sent in their images, videos and sounds to the project. Duncan Kennedy reports from Mexico City: Listen to the story Contacting outer space has been an obsession for humans for thousands of years. Well now, this new project aims to make an attempt on behalf of the digital generation. Organised by the internet search engine Yahoo, material has started to be collected from around the planet. Under the section 'what makes you sad', a man from Ethiopia has sent in a letter with the word 'greed' written on it. In the 'what is fun' section, a man from Toronto has posted a picture of himself poking his tongue out. The majority of contributions so far are about the subject of love. A panel of judges will decide the final content to be digitalised. Then, later this month, the chosen work will be projected via a laser onto an ancient pyramid on the outskirts of Mexico City and then into space. The site was chosen because of the contrast between old and new civilisations. The organisers say information has never been captured on such a scale before and will show anyone or anything watching what life is really like on earth. Time capsules have long been a favoured tool of humans to pass on their legacy. In the 1970s, the astronomer Carl Sagan famously compiled a record. It included the sound of a mariachi band and greetings in an ancient Sumerian language. The record was sent out on the Voyager spacecraft. This latest attempt to speak to any potential neighbours may be earthbound. But in what is being described as the first ever digital mosaic of humanity, it hopes to harness the power of lasers and the internet to cross the inter-galactic divide.
