Here's a link to the image:

Click on it and see how big this survey is for a small section of the sky they are doing.  Each dot is basically a galaxy with billions of stars.  Things like this are just cool to me as they remind me of how vast our universe really is.  Truly we live in a wondrous time as we continue to expand our knowledge of the universe of which we are but a small part.

Here is an article on the information:

I thought it was rather cool. _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com
