The extended study will complete Sloan's main mission, to obtain images and distances of I million galaxies and quasars. The 2.5-meter Sloan telescope, located at Apache Point Observatory near Sunspot, N.M., can lock on to type 1a supernovas at distances ranging from 1.3 billion to 5.2 billion light-years, notes Andy Becket of the University of Washington in Seattle. Observations of these supernovas may provide clues about the character of dark energy, including its effect on the overall curvature of the universe.
