Dr. Seth Shostak is Senior Astronomer at the SETI Institute in Mountain View, Calif. He claims to have developed an interest in extraterrestrial life at the tender age of ten, when he first picked up a book about the Solar System. This innocent beginning eventually led to a degree in radio astronomy, and now, Seth is an enthusiastic participant in the Institute’s SETI observing programs. He’s co-authored a college textbook on astrobiology, and has written three trade books on SETI. In addition, he’s published more than 400 popular articles on science including regular contributions to NBC News MACH, gives many dozens of talks annually, and is the host of the SETI Institute’s weekly science radio show, “Big Picture Science.” He has received the Carl Sagan Award for the Popularization of Science and the Klumpke Roberts Award for Astronomy Popularization.
