This spring, the Hubble outreach office started a Hubble Treasure Hunt
The challenge was to browse through the Hubble raw data archives, and look for undiscovered images, ones that had not been published and were interesting or beautiful.
There are a lot of Hubble images.
The finalists for the contest have now been announced, in two different categories: one for unprocessed images; the other for processed images.
there are beauts in there, go vote!
