Cardinals are returning to the Sistine Chapel to continue voting for a new pope. The first conclave ballot failed to find a winner, sending black smoke through the chapel chimney.

As cardinals gather at the Sistine Chapel to begin voting 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 conclave to select the next pope has begun after Catholic cardinals from across the world filed into the Sistine Chapel Wednesday before sealing themselves inside.
