Photos: Conclave - Day 1

Black smoke billows out from a chimney on the roof of the Sistine Chapel indicating that the College of Cardinals have failed to elect a new Pope. Benedict XVI's successor is being chosen by the College of Cardinals in Conclave in the Sistine Chapel. The 115 cardinal-electors, meeting in strict secrecy, will need to reach a two-thirds-plus-one vote majority to elect the 266th Pontiff. (Photo by Peter Macdiarmid/Getty Images)
