Is There Life on Other Planets?


 Last Sunday, May 25, 2008, the Phoenix cleaved through the Martian atmosphere and landed successfully on the planet’s northern polar region.  In what was obviously a very historic moment, the lander sent back crisp, clear pictures of the region’s polygon-cracked terrain.  It sent shivers down my spine.

             So the questions “Are we alone?” or “Is there life out there?” are becoming more and more familiarly conventional questions in this age of rapidly increasing, and enlightening, scientific discoveries; we’ve definitely come a long way from the time Galileo was disgraced by the Church for claiming that the Earth is not the center of the universe.            

             How big really is the universe?  You’d probably say, it’s really, really big.  But really, how big?
