  Here's something for you to look at. While you do, think of this: In our universe there are countless galaxies. In each galaxy, there are countless stars. Stars are.. well.. suns. Each sun probably have their own solar systems. We live in one of the planets in one of those solar systems.
  
  The Sombrero Galaxy, one of the largest galaxies in the nearby Virgo Cluster of Galaxies, spans about 50,000 light years across and lies 28 million light years away. The Sombrero can be seen with a small telescope in the direction of the constellation Virgo.
  
  
  
  
  
  
  
  
  
  
  
  
  
  Adrift 1,500 light-years away in one of the night sky's most recognizable constellations, the glowing Orion Nebula and the dark Horsehead Nebula are contrasting cosmic vistas.
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  This stunning group of galaxies is far, far away - about 450 million light-years from planet Earth - cataloged as galaxy cluster Abell S0740. The giant elliptical galaxy spans over 100,000 light years and contains about 100 billion stars, comparable in size to our own spiral Milky Way.
