Dr. Phillips is presently involved in a new two-part, 5-year project called the Carnegie Supernova Program (CSP), which is obtaining light curves of approximately 100 nearby type Ia supernovae in the optical and infrared bandpasses. The use of the infrared is especially important, since the effect of interstellar dust absorption -- a major source of uncertainty when deriving supernova distances -- is greatly reduced. This sample will then provide a comparison for near-infrared observations of about 50 more distant type Ia supernovae, whose distances will then be derived for a new measurement of the acceleration of the universe. The program should provide further clues to the nature of the mysterious ``dark energy'' that is presumed to be driving the acceleration.
