A once-in-a-lifetime nearby stellar explosion now unfolding in a neighboring galaxy has astronomers at the W. M. Keck Observatory scrambling to ask questions that can’t be answered at any other ground-based telescope in the world. The first big question: What causes this pivotally important type of stellar cataclysm?

Observing this spectacular supernova, dubbed PTF11kly, began on August 24, with the detection of the explosion in the nearby Pinwheel Galaxy, a.k.a. M101, by the automated Palomar Transient Factory (PTF) survey. That survey is designed to detect short-lived astronomical events as they happen.

A supernova discovered Wednesday is closer to Earth ––approximately 21 million light years away –– than any other of its kind in a generation. Astronomers believe they caught the supernova within hours of its explosion –– a rare feat for events of this type.

The discovery of a supernova so early in its life, and so close to Earth has energized the astronomical community. Scientists around the world are scrambling to observe it with as many telescopes as possible, including the Hubble Space Telescope, and telescopes from the UC Santa Barbara-affiliated Las Cumbres Observatory Global Telescope Network (LCOGT).
