This week started off with the nightmare ending for Amanda Knox, after her murder conviction was overturned and she was released from Italian prison. On Wednesday, the Duchess of Alba, 85, and her 61-year-old beau tied the knot after she gave up her fortune to prove their love was no money-grabbing gimmick. But sadly all of the news wasn't so happy this week; Steve Jobs lost his battle with cancer, and we lost the man who launched the Apple legacy. The week ended on a positive note, however, as three women were awarded the Nobel Peace Prize. See all this and the other headlines you might have missed in our week in pictures.
