Cardinals failed again Thursday morning to find a successor to Pope Francis, sending black smoke billowing up through the Sistine Chapel chimney after two more inconclusive rounds of conclave voting.

As cardinals gather at the Sistine Chapel to vote for a successor to Pope Francis, there is no single frontrunner, and it remains unclear whether the new pope will align with Francis’s more inclusive ideology.

The largest and most geographically diverse conclave in history is due to resume, with Roman Catholic cardinals returning to the Sistine Chapel to try to settle a wide-open papal election.
