Introduction

Who has not wondered if life exists outside the confines of our solar system?  I know that this question has plagued astronomers for many centuries as they tried to explain the complexities of the galaxy.  Are there others?  What is their life like?  Are they green like the caricatures that we have seen on television and in the magazines?  Are they waiting to attack us as soon as the opportunity arises?  These are just a few of the questions that people have pondered for many ages.  I know these questions to be true because I have wondered these questions myself.

As a Science Teacher, I have always been fascinated with the unknown mysteries that space presents.  I have wondered if perhaps the rumor that the government is housing aliens in Area 51 is true, or whether it is just a myth that was created by Hollywood to sell movies.  Who has not looked up into the sky and surmised that they just witnessed an Unidentified Flying Saucer (UFO) which was about to invade our solar system?  I remember when I was a child growing up in the old neighborhood, we were playing out in the street one hot and sticky summer night and we witnessed something in close proximity about to land.  Our first thought was that we were about to witness a UFO invasion.  These are truly the beginnings of a really good sci-fi flick, “The Night the Aliens Landed”.  The street was very dark on this particular night and there was an ominous feeling in the air.  We were all mystified as we waited to see what would happen next!  As I look back on this memory, I feel as though we should have really proceeded home as fast as we could, but we did not. What we had just witnessed as it turned out was not an alien UFO but a dirigible, a Goodyear Blimp.  This blimp had landed in the field directly behind our houses. I can certainly tell you that if we would have run home that night the story would have been much different than what I am describing right now.  My memories as seen through my child eyes would have described it as the night we were invaded by aliens.  The story could have been a bestseller!
