Astronomers seek to understand the overall role of supernovae in cosmology, and the dimensions and history of the universe.
The Katzman Automatic Imaging Telescope (KAIT) is programmed to search robotically for distant supernovae on every clear night of the year. If KAIT "sees" differences in luminosity within a galaxy, indicating a possible supernova, it notifies astronomers, who investigate further using the Kast spectrograph.
Watch Dr. Alex Filippenko, Professor of Astronomy at University of California, Berkeley, discuss supernovae and black hole research at Lick Observatory.
