If you have never visited the Hubble Gallery at Hubblesite.org, you own yourself the time. It’s pretty much the best space website out there, very well organized with jaw-dropping images and some of best animations.
I’m currently downloading and cataloging thousands of Hubble images for use in the “Evolution of the Universe” part of “Outside In”. I have 200 files so far and will end up with many thousands. It’s probably about 4 months of work by the time the animation is complete.
