International Year of Astronomy 2009 Public Talks

Hosted by the UC Berkeley Astronomy Department

The Astronomy Department at UC Berkeley presents a public lecture series in celebration of the International Year of Astronomy 2009. Talks take place from 11am until 12 noon on the third Saturday of each month.

Doors open thirty minutes before the talk and seating is on a first-come, first-served basis. We would like to start the talks on time, and avoid disruption from people entering the auditorium during the talks, so please try to arrive at least 10 minutes before the start. Admission is free, but if you wish to support astronomy at UC Berkeley, you can donate here.

To sign up for our email list and receive notification about future talks, and other news from the UC Berkeley Astronomy Department, please visit our mailing list page and enter your email details. We won't sell or give away your email and we won't send you lots of messages.

Talk Series

The talks take place in the Genetics and Plant Biology Building, Room 100 (map square B-2). The December talk takes place during examinations at Berkeley and the venue will be announced closer to the date.

Limited hourly pay parking is available on weekends on and nearby campus - please check the signs. We encourage you to take public transport - BART and bus lines are within walking distance.

Our next talk - Maryam Modjaz - Saturday, November 21, 2009: "Cosmic Fireworks: The Explosive Deaths of Massive Stars"

Maryam Modjaz is a Miller Postdoctoral Fellow in Astronomy at UC Berkeley. She works on the explosive deaths of massive stars as supernovae and gamma-ray bursts. The recipient of Harvard University's Fireman Prize for an outstanding PhD dissertation, her work has been featured on National Public Radio, in the Christian Science Monitor, Astronomy Now, and in a feature article in UC Berkeley's "California" magazine.

Massive stars die violently. They produce the most powerful explosions in the Universe during their death-throes: supernovae and gamma-ray bursts. Supernovae are brilliant firework displays that become as bright as a billion suns combined, and gamma-ray bursts are monster explosions that launch jets moving nearly at the speed of light and outshining the whole gamma-ray Universe in a few seconds. Both explosions produce and expel heavy elements and an enormous amount of energy; they leave behind fascinating objects like black holes and pulsars, and like beacons they are visible over billions of light years across the vast Universe.

How are these types of explosions related? Are they dangerous to life on earth? How may they be vital for life on earth? These are some of the questions Dr. Modjaz will discuss during her breathtaking tour of the most powerful explosions of the Universe.
