In this June 25, 2007 file photo photo provided by the Vatican newspaper L'Osservatore Romano, Pope Benedict XVI leafs through a book of documents of the trial of Italian astronomer Galileo Galilei (1564-1642), part of the collection of books of the Vatican library, during his visit to the Vatican's secret archives. Galileo Galilei is going from heretic to hero. The Vatican is rehabilitating its most famous victim of the Inquisition, just in time for the 400th anniversary of Galileo's telescope and the U.N.-designated International Year of Astronomy next year.
