Kepler's Quest for New Worlds Public Talks - SOLD OUT

Catching Shadows: Kepler's Quest for New Worlds

Humankind's speculation about the existence of other worlds like our own turned into a veritable quest with the launch of NASA's Kepler spacecraft in March 2009. The mission is designed to survey a slice of the Milky Way to identify planets orbiting other stars. It looks for the telltale dimming of light that occurs when an orbiting planet passes in front of the star thereby casting a shadow into space. The roster of exoplanets discovered by Kepler has reached close to 30 in number, including one world that is unquestionably rocky in composition, another with 6 transiting planets, and another in a circumbinary orbit. Moreover, the team has released a catalog of nearly one thousand stars showing the recurring dimmings of light that suggest the presence of a planet. The methods used to identify planets will be described in this talk as well as the discoveries that have been announced to date. Now in its third year of operation, Kepler is honing in on the answer to the question that drives the mission: are potentially habitable worlds abundant in our galaxy.

Speaker: Dr. Natalie Batalha,professor of physics and astronomy at San Jose State University and the deputy science team lead for NASA's Kepler Mission.

Songs of the Stars: the Real Music of the Spheres

We humans are visual creatures. For us "seeing is believing." The Pythagoreans 2500 years ago believed in a celestial "music of the spheres", an idea that reverberated down the millennia in Western music, literature, art and science. Johannes Kepler (the namesake of the Kepler Mission) was so enamored with Pythagoras's idea that in the early 1600s that he spent years trying to discover harmonic relationships among the periods of the planets in their orbits about the Sun, finally, disappointingly (for him), proving otherwise. Now we know that there is a real music of the spheres. The stars have sounds in them that we can use to see right to their very cores. This multi-media lecture looks at the relationship of music to stellar sounds. You will hear the real sounds of the stars and you will hear musical compositions where every member of the orchestra is a real (astronomical) star! You will also learn about some of the latest amazing discoveries from the Kepler Space Mission that lets us "hear" the stars 100 times better than with telescopes on the ground.

Speaker: Dr. Don Kurtz, professor of astrophysics at the University of Central Lancashire in the United Kingdom and a steering committee member of the Kepler Asteroseismic Science Consortium.
