Black smoke appeared from a chimney atop the Sistine Chapel at the Vatican on Thursday, signaling that cardinals meeting in a secret conclave did not elect a new pope during their two morning ballots.

The cardinals held an initial inconclusive vote on Wednesday evening.

Everything to know about the conclave

• A conclave is a meeting between cardinals that will privately select a new pope.
• 133 cardinals from around the world have entered the Sistine Chapel for the selection process, and will be the most geographically diverse in history.
• The process could last several days, with the average duration based on the past conclaves lasting roughly three days.
• Ballots will be cast beginning at 4:30 p.m., and a chimney will carry white smoke to announce that a new pope has been chosen, or black if inconclusive. A two-thirds majority vote is required to pick a successor.
• On May 8, white smoke was seen coming out of the Sistine Chapel chimney, signaling the College of Cardinals had chosen a successor.

They now hold two votes in the morning and two in the afternoon daily until someone wins the necessary two-thirds majority to become the next pontiff.
