VATICAN CITY — Black smoke is pouring out of the Sistine Chapel chimney, indicating no pope was elected on the first ballot of the conclave to choose a new leader of the Catholic Church.

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.

The great doors of the Sistine Chapel shut Wednesday after the cry of “extra omnes” — Latin for “all out” — as 133 cardinals began the secretive, centuries-old ritual of electing a new pope to lead the Catholic Church, opening the most geographically diverse conclave in the faith’s 2,000-year history.

The red-robed cardinals entered the Sistine Chapel in pairs.
