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.

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

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.
