SN 2011fe in Pinwheel Galaxy (image) DOE/Lawrence Berkeley National Laboratory Caption Supernova 2011fe was discovered by the Palomar Transient Observatory just hours after it exploded in the Big Dipper. Studies by the Nearby Supernova Factory of its colors and spectrum as they evolved over time have produced a benchmark atlas of data by which to measure all future Type Ia's.
