The Impact of Discovering Life beyond Earth

Steven J. Dick held the 2014 Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology at the John W. Kluge Center of the Library of Congress. In 2013 he testified before Congress on the subject of astrobiology. He served as the Charles A. Lindbergh Chair in Aerospace History at the National Air and Space Museum (2011-2012), and as the NASA Chief Historian and Director of the NASA History Office (2003-2009). He is the recipient of numerous awards, including the NASA Exceptional Service Medal and the Navy Meritorious Civilian Service Medal, and is author or editor of twenty books, including The Biological Universe (1996). He was awarded the 2006 LeRoy E. Doggett Prize for Historical Astronomy of the American Astronomical Society.

'Are we alone in the cosmos? If yes, we can never be sure. If no, we might well have an answer within the decade. The 22 authors of these fascinating and informative essays say no, we are not alone, despite the fact that so far not a shred of evidence has been found for the existence of life elsewhere in the universe. But just in case they are right, we need to start thinking about the possibility that we are not alone, and here is a good place to start.' Owen Gingerich, Harvard-Smithsonian Center for Astrophysics and author of God's Planet
