7 PM - FREE showing of Cosmic Collisions in the Albert Einstein Planetarium. This half-hour planetarium show  launches visitors on a thrilling trip through space and time - well beyond the calm face of the night sky - to explore cosmic collisions, hypersonic impacts that drive the dynamic and continuing evolution of the universe.

7:30 PM - Meet the Lecturer

8 PM - Lecture

The Kuiper Belt is a mysterious region beyond Neptune and stretching more than four billion miles from the Sun. Using powerful telescopes, scientists are scouring the Belt and beyond, finding hundreds of small frigid objects such as Eris, which is larger than Pluto and takes 560 years to orbit the Sun; and smaller Sedna, with an elliptical orbit that takes more than 10,000 years to complete. Join Mike Brown as he describes the hunt for these ancient and elusive worlds.

Mike Brown is Professor of Planetary Astronomy at the California Institute of Technology and the discoverer, along with colleagues, of Eris (formerly 2003 UB313), Sedna, and other distant bodies.

This lecture is free, but tickets are required.

The 2007 Exploring Space Lectures, Journey Through the Outer Solar System, will feature four world-class scholars discussing current missions to the distant realm of the gas giants, the icy Kuiper Belt, and beyond.
