Comet Hale-Bopp Yields Secrets In The Infrared, Cornell-NASA Investigators Say
Using a combination infrared spectrometer and camera designed and built by Cornell University researchers and attached to the 200-inch telescope at Palomar Observatory, Cornell and NASA scientists have made ground-based measurements in an effort to learn what kind of stuff Comet Hale-Bopp is sloughing off as it approaches perihelion, to learn more about the makeup of the celestial visitor and, perhaps, the origins of the solar system
