Are there know, out there? What are the chances of life appearing somewhere, anywhere, in the universe? Will we get to say "hi" and have a chat? Is there any life in our own solar system (uh, besides on earth)? I discuss these questions and more in today's Ask a Spaceman! 

Keep those questions about space, science, astronomy, astrophysics, and cosmology coming to #AskASpaceman, Twitter@PaulMattSutter,, and for COMPLETE KNOWLEDGE OF TIME AND SPACE! Music by Jason Grady and Nick Bain.
