You Are Here Galaxy.  Postcard.

Perspective. Our galaxy contains 100-400 Billion Stars, plus 100 Billion planets.  Light coming from the center of our galaxy left there 30,000 years ago. 

There are about 200 Billion other galaxies in the observable universe.  While there are many other planets, this is the only one we are certain supports life.  The universe is huge, our place in it is small, the balance is fragile.  Breathe.
