Satellite TV 'making humans invisible to aliens on other planets'A Telegraph article reports on a claim by the world's leading ET hunter that Satellite television and the digital revolution is making humanity more and more invisible to inquisitive aliens on other planets. The article continues: That might be good news for anyone who fears an ''Independence Day'' – style invasion by little green men. But it is also likely to make the search for extraterrestrial intelligence by Earthly scientists harder, Dr Frank Drake believes. Dr Drake, who founded the SETI (Search for Extraterrestrial Intelligence) organisation in the US 50 years ago, said the digital age was effectively gagging the Earth by cutting the transmission of TV and radio signals into space. At present, the Earth was surrounded by a 50 light year-wide ''shell'' of radiation from analogue TV, radio and radar transmissions, he said. But although the signals had spread far enough to reach many nearby star systems, they were rapidly vanishing before the march of digital technology. To a race of observing aliens, digital TV signals would look like noise, said Dr Drake. Digital transmissions were also much weaker than their terrestrial equivalent. While old-style TV transmitters might generate one million watts, the power of a satellite signal was around 20 watts. Satellites also aimed their transmissions at the Earth, with almost none being allowed to escape into space
