Every dot in this image is a star! Over
500 million stars in the Andromeda Galaxy as seen by Hubble space telescope! 
for every grain of sand on the planet Earth, there is millions of stars in the universe!! Think about that for a moment, when you think of how relative we are to the entire Cosmos! The lead in your blood came from the center of a star, after imploding in on itself and spewing out the periodic table as we know it! It's very interesting to see and think about corporations, like Boeing, spaceX, ect.., and where they will take us in the next hundred years!
