Sworn to complete secrecy, the 115 Cardinals in Rome will vote again on Wednesday (March 13) for a new Pope to replace Benedict. Black smoke billowed from the Sistine Chapel after the first round of voting, meaning no new Pope had been elected. Once one candidate receives a two-thirds majority, he becomes Pope, and the first sign the Cardinals were successful is when white smoke comes from the Chapel’s chimney.

So until the voting process is complete, the Cardinals will remain in isolation and not allowed to communicate in any way with the outside world. To insure that no social media is used, jamming devices are in place to prevent any mobile phones or other electronic devices from being used.

The longest conclave since the start of the 20th Century took five days to elect a new Pope.
