This photograph shows a collection of 200 billion suns - a galaxy. It would take hundreds of years using our most advanced propulsion systems just to travel between any two of its suns. Millions of years to travel across its diameter. There are1.2 trillion galaxies in the observable universe. Maybe we can gain perspective as humans on earth from this, realize the immensity of what we are up against, learn to respect our fragile planet, and just get along.
