SETI: 50 years of searching for ET

Publication: MSNBC.com   Date: April 26, 2010   View Article

Somewhere out there, alien civilizations might be communicating with each other. They might even be trying to contact us. Fifty years ago, this reasoning compelled astronomer Frank Drake to point a radio telescope at the stars and listen for chatter. He didn’t hear E.T. calling us, calling home, or calling anywhere else during his four-month-long experiment at the National Radio Astronomy Observatory in Green Bank, W.Va., but the effort officially kicked off what is known as SETI, the search for extraterrestrial intelligence.
