Pedro,
The observations you note are discussed in the comments of the blog entry at
http://skyview.gsfc.nasa.gov/blog/index.php/2009/04/29/features-in-the-gallery-sometimes-you-can-do-better/.
You see two images of Saturn because the image shown in the IRAS survey adds together two separate scans (three for some parts of the image) separated by a few weeks in time. Saturn moved a bit between the two scans.
Regards,
Tom

Sorry for the long delay. You may be thinking of supernovae which are exploding stars. Stars like our sun do not have enough mass to go supernova. They expand to red giants with a dense core and the very large but tenuous outer atmosphere. Eventually they blow off the atmosphere and the core turns into a white dwarf. The blown off atmosphere becomes a planetary nebula until it disperses.

Never knew that there was a planetary nebula named Saturn, I always though that planetary nebulae was exploded stars forming new stars and planets?
