catdynamics | August 6, 2012This 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.

The finalists for the contest have now been announced, in two different categories: one for unprocessed images; the other for processed images.
The decision on the winners, will be done by public vote, and the selection of finalist images is up on the web and open for voting:
unprocessed images are here

Saturn is right next door.

Apologies in advance for a very Warning - a proudly Canada-centric post today. First, a bit of background - we Canadians pay two kinds of sales tax. The goods and services tax (5%) which is consistent across Canada, in addition to provincial sales taxes that varies from location to location (with the exception of Alberta, which has no provincial sales tax at all).
