On Thursday, the 133 cardinals are expected to vote up to four times in the hunt for a new pope.
In the morning, black smoke rose again from the Sistine Chapel's chimney, just like after the very first round on Wednesday evening.
During the conclave, the cardinals usually vote in the morning and two times in the afternoon, but smoke is only sent up twice a day.
To be elected pope, 89 votes are required – a two-thirds margin. Black smoke means that the cardinals have not managed to agree on a candidate. When a pope is finally elected, white smoke will instead pour out of the chimney.
Pope Francis died on April 21, 88 years old. Since then, the cardinals have arrived one by one in Rome. On Wednesday afternoon, they were locked into the Sistine Chapel near St. Peter's Church to elect a new pope.
