“The probability of success [in discovering extraterrestrial life] is difficult to estimate, but if we never search, the chance of success is zero.” 

—  Physicist Philip Morrison

At some point in our lives, we are confronted with something we fear is larger than ourselves, and with nowhere else to turn, we peer up to the heavens. There are also those among us who look there first and hold that gaze for a lifetime.
