I agree it does seem strange that some images are repeated when there is such a wealth of original material available.

BMAONE23, that's a good theory, but please rest assured the APOD folks are receiving far more unique images than they are publishing. Many, many astroimages are produced by amateur astronomers worldwide each day, and ever more are of astonishing quality as the equipment continues to improve.

If you pick any particular image like this http://antwrp.gsfc.nasa.gov/apod/ap070202.html of the Flame Nebula, then if you go back to the archive page http://antwrp.gsfc.nasa.gov/apod/archivepix.html and using the search feature http://antwrp.gsfc.nasa.gov/cgi-bin/apod/apod_search enter Flame Nebula and run the search you will find several instances of different repeated images http://antwrp.gsfc.nasa.gov/cgi-bin/apo ... ame+nebula
The same holds true for any search of a known image.
I believe that this is caused by the fact that many imaging hours are required by individual telescopes to create these astounding images.

Remember there are only 86,400 seconds in a day so a million second exposure takes about 2 weeks to produce.

Some may not be aware of the Archive of APOD. Also the manipulation of certain photos in sequence becomes apparent too. Just to promote some far fetched theory.

Yes, they sometimes present the same images several times. I suspect it is so that people who happened to miss truly inspiring images with interesting facts the first time around will get a chance to see them when they go back up. I know I've seen several my first time that way.

Also note that the APOD pages go into a very nice book. It's possible they want to have certain images and descriptive text make it into a particular edition of the book.
