The Nearby Supernova Factory




Data Releases




For Students






The Nearby Supernova Factory (SNfactory) is an experiment to develop Type Ia supernovae as tools to measure the expansion history of the Universe and explore the nature of Dark Energy. It is the largest data volume supernova search currently in operation.

The SNfactory is an international collaboration between several groups in the United States, France, Germany and China including Lawrence Berkeley Lab and Yale University in the United States, the LPNHE, IPNL, CRAL, and LPC IN2P3/CNRS labs in France., The Max Planck Institute for Astrophysics and Humboldt University in Germany, and Tsinghua Center for Astrophyiscs in China. The experiment is designed to address a wide range of supernova issues using detailed observations of low-redshift SNe.

spectroscopically-confirmed supernovae
discovered by the SNfactory surpassed 600!
