Cardinals enter the Sistine Chapel to begin the conclave in order to elect a successor to Pope Benedict, in a still image taken from video at the Vatican March 12. Shut off from the outside world, the 115 cardinals will cast their ballots in a chapel which has Michelangelo's soaring Last Judgment on one wall, and his depiction of the hand of God giving life to Adam above them.

Cardinals enter the Sistine Chapel on Tuesday to elect the next pope amid more upheaval and uncertainty than the Catholic Church has seen in decades: There's no front-runner, no indication how long voting will last and no sense that a single man has what it takes to fix the many problems.
