As I had announced in my blog, I spent four days in Oslo before Easter, visiting museums with my kids and my fiancee, and enjoying the place -new to all of us.

Today I am leaving to Norway, for a visit of few days. If you happen to have suggestions for things to see and do there, please drop me a line in the comments thread below; I will be traveling with my son Filippo (13 yo) and daughter Ilaria (9), so avoid advising me on night clubs or wine bars; museums and entertainment are more like what I am likely to be interested in.

Also, if you live nearby and are (presumably) interested in particle physics, I will be happy to have a drink together. I'll tell you the news from the LHC experiments, you can in return give me information about the place. My phone number is 0039-3468671707.

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).
