That's awesome...besides relative sizes I've also been boggled by the vast number of suns in the cosmos and what that could mean...the latest estimate from the General Assembly of International Astronomical Union is that there are 70 sextillion stars...or suns...in the observable universe...that is 70,000,000,000,000,000,000,000 suns and still counting...we know how stars are born and how planets are formed from left over material as gas and dust coalesce to form the center of a solar system...with that many suns...and we know that planets revolve around these suns much like our solar system...then a number of planets could fall into a zone where life could evolve relative to their own sun...you can do the math but if only 1 in a million of these planets meet the requirements for life to exist and we add billions and billions of years to the equation then the probability of other life out there approaches near certainty.

Let's just hope they dont all decide to emigrate to the USA.
