The Hubble Legacy Archive is now open for you to browse ! Thousands of unscrutinized images of the sky as pictured by the Hubble Space Telescope are there for you to browse, reprocess, analyze. They even challenge you to find hidden treasures, and submit them for their scrutiny. It is a marvelous opportunity to get personal with all the beauties of our cosmos. There is an online tool for changing colours and contrast of each picture.

Have a look at what you can find with just seconds of searches: the picture below portraits one of my favourite targets in late summer nights, Stephan's quintet (here shown only four of the main components).
