In August 1977, the Big Ear Radio telescope in Ohio received a strange signal from the Sagittarius constellation while searching for intelligent extraterrestrial life. It had a duration of 72 seconds and an intensity 30 times higher than usual. Named the WOW signal (as an engineer wrote WOW on the data as it came in!), it is still being considered as one of the best examples of having been sent a signal from intelligent extraterrestrial life. But, nothing has revolutionized the search of extraterrestrial intelligent life as much as the recent discovery by the Kepler Satellite of thousands of Earth-like planets where life could be possible.
