Shooting for the moon: the Saudi spotting teams that herald Ramadan
Deep in the Saudi Arabian desert, a group of robed men are peering into the sky, trying to spot the crescent moon that signifies the start of Ramadan.
Their work is significant: an official sighting of the moon begins a month of fasting and prayer for millions of Muslims in Saudi Arabia, the home of Islam's holiest sites, and beyond.
"I feel a great responsibility, before God above all... and I seek success because the matter is related to the fasting of all Muslims," said Abdullah al-Khudairi, director of the Majmaah University Astronomical Observatory.
