Cardinals are back inside the Sistine Chapel for another round of voting on day two of their conclave to elect a new pope.
They took a break for lunch after this morning's round of voting ended with no new pope selected.
It's the second time since conclave began that black smoke came out.
The smoke was seen yesterday after the first round of voting ended with no new pope.
Now with speculation mounting, some candidates could be moving to the top of the list.
They include Cardinal Angelo Scola of Milan, Cardinal Odilo Pedro Scherer of Brazil, and Cardinal Marc Ouellet of Canada.
An American shadow candidate like New York's Cardinal Dolan or Cardinal Sean O'Malley of Boston could also slip in if there's no consensus on anyone else. As a result, the third and fourth rounds of voting are considered important.
The balloting process will continue each day until a candidate at least 77 votes.
If no pope is elected by Friday, the cardinals will take Saturday off before resuming on Sunday.
