From its perch atop Hawaii’s dormant Haleakala volcano, the PS1 telescope, which boasts the world's largest digital camera, has begun full-time operations, snapping hundreds of high-resolution photos each day as it scans the sky for space rocks and strange stellar phenomena. PS1 is the first of several telescopes planned as part of the Panoramic Survey Telescope & Rapid Response System, or Pan-STARRS. The telescope will map near-Earth asteroids ranging in size from 984 feet (300 meters). (source: news.nationalgeographic.com)
