Seth Shostak

As Senior Astronomer at California's SETI Institute, he is involved in what is perhaps the greatest voyage of discovery ever undertaken: the search for other intelligent beings in the cosmos.While many credulous people believe that UFOs from other worlds are buzzing the countryside, or possibly abducting unsuspecting folk for unauthorized experiments, Seth and his colleagues are searching for aliens using the best methods of science. They wield massive telescopes in a search for signals from deep space - signals that would prove that we're not alone. These efforts were described in Carl Sagan's novel and movie, Contact. [+]
