IN this week's show we discuss the search for life on other planets. Should we be trying to contact possible civilizations without knowing what exactly is out there? Has life elsewhere already contacted us? Can we take this concept and integrate it into the Biology classroom? What is the six degrees of separation that connect Buzz Aldrin and the most famous alien in history? Finally, we will see if you can guess the gizmo that I bet you've used at least once in the last week.
