The telescope shown here is the first of four Pan-STARRS telescopes to be built on the summit of Haleakala, a volcano on the island of Maui. The complete Pan-STARRS system will use the world's largest digital camera—with 1.4 gigapixels—to survey the entire sky visible from Hawaii roughly once a week. This vast survey is expected to discover thousands of supernovae, greatly increasing the number of data points on the Hubble diagram and therefore increasing the precision with which we know the expansion history of the universe and its acceleration rate.
