The smoke billowed out at 9 p.m. Wednesday, some four hours after 133 cardinals solemnly entered the Sistine Chapel, took their oaths of secrecy and formally opened the centuries-old ritual to elect a successor to Pope Francis to lead the 1.4 billion-member church.
With no one securing the necessary two-thirds majority, or 89 votes, the cardinals will retire for the night to the Vatican residences where they are being sequestered.
They return to the Sistine Chapel on Thursday morning when it's expected there will be several votes.
