Free Public Astronomy Talk: Quasars

Because the extremely bright, distant objects known as quasars can be seen from so far away, they offer researchers a unique opportunity to peek farther back in time than is offered by other celestial phenomena. Current theories suggest that because they expel jets of energetic particles and emit at radio wavelengths, and because the energy involved is so great, there must be a supermassive black hole at their center, but the details of how it all works is still a mystery. UC Santa Barbara Professor Robert Antonucci, Ph.D., will discuss these mysterious bright objects that lurk at the heart of distant galaxies.

Join us at the Santa Barbara Museum of Natural History for this free public talk in Fleischmann Auditorium, presented by the Santa Barbara Astronomical Unit. No registration required.
