August 5           General Meeting       "Gravitational Lensing - The Telescope of the Universe" by Tom Eason 
                         Tom described how the fact that massive celestial objects such as galaxies bend light passing in their vicinity results
                         in them acting like giant telescope lenses. This makes it possible to detect and study extremely distant objects not
                         easily accessible to man-made telescopes.

June 3               General Meeting       "How to Imagine the Universe" - An Introductory  Talk on Cosmology by Prof. Milan Mijic
                         (professor at CSU Los Angeles and Sierra Community College)

                         A hundred years ago it was believed that we live in an eternal, dark, mostly empty space, sprinkled with stars and
                         filled with ether that carries light and radio waves. Now we know that we live in an expanding, evolving universe,
                         larger and more complex than we ever imagined. Milan explained the modern picture of the universe, and how
                         astronomers arrived at it.
