Two planetary scientists and an astrophysicist make the case that the search for life in other parts of our universe has been made all the more valid by two recent discoveries, one taking place at the bottom of our oceans and the other around stars in our galaxy.  As it turns out, life thrives without benefit of any sunlight along mid-ocean ridges, one of earth’s most inhospitable places.  And, improvements in telescope technology have revealed the presence of dozens of new planets circling stars similar to our own sun.  The discussion then turns to the feasibility and value of finding proof that extraterrestrial life exists.  All predict our inherent inquisitiveness and daring will lead to such an expedition into space within the next 15 years, providing the necessary funding is made available.
