SETI scientists say it's time to send messages to ET

Scientists want to contact extraterrestrial civilizations. Some applause the effort. Others say this is not a good plan at all. The idea is for messages encoded in radio signals to be sent repeatedly for hundreds of years to planets in habitable zones around stars, said a report in The Guardian. Repeated signals would be beamed at nearby planets that were chosen for their odds of harboring life. The scientists are from the Search for Extraterrestrial Intelligence (SETI) Institute in California.
