Asteroid Lecture Tonight

In case you are also here in San Francisco during the AGU meeting: tonight is a free public lecture, "Near Earth Comets and Asteroids: Finding Them Before They Find Us" 7:00 PM at the Exploratorium. The museum at 3601 Lyon Street (around the corner from Palace of Fine Arts) is a fun place to visit. The city is decked out in holiday lights--so much for "dark energy!"
