The conclave is set to begin May 7, but the public only knows its end by iconic white smoke billowing out of the Sistine Chapel’s chimney.
Black smoke means the cardinals have not yet reached the two-thirds majority vote necessary to elect a new pope. The cardinals burn the ballots in a stove, adding chemicals to the fire to color the smoke.
The best place to watch for the smoke is in St. Peter’s Square itself, but the Vatican will also livestream the smoke on its YouTube channel, Vatican Media Live.
