The size of the universe

There are over 200,000 galaxies in this picture alone, each containing billions of stars. This picture represents a very small portion of the sky. The size of the universe really is incomprehensible.

This view shows a section of the widest deep view of the sky ever taken using infrared light, 
with a total effective exposure time of 55 hours. This picture shows a region of the sky 
known as the COSMOS field in the constellation of Sextans (The Sextant). 
More than 200,000 galaxies have been identified in this picture.

Click here to see the full size version-- fair warning, it's a pretty big file (8.8 mb).
