How big the universe
Here is a piece of the sky made by the Hubble telescope and processed with data collected over 10 years.

Under the cut a bit more.
This piece of heaven at the arrow is only 1/13, 000, 000 of the total area of the sky (for comparison is next to the moon). This includes part of the sky 800 shots at a 20-minute exposure of each fragment. For images of the entire sky with a sensitivity of Hubble it would take millions of years.
