The 133 cardinals tasked with electing the next leader of the Catholic Church had their first vote on Wednesday.

More than 130 cardinals from all over the world are gathering today for the papal conclave, through which a new head of the Catholic Church is elected.

A new pope will be selected when a candidate gets a two-thirds-plus-one majority vote by the cardinal electors. White smoke will be sent up the chimney of the Sistine Chapel when that happens, to indicate a new pope has been chosen.
