Extraterrestrial impacts and their importance to the Earth's, and Alabama's, history will be the topic at the Tuesday, July 19, meeting of the Birmingham Astronomical Society. The public is invited to the 7 p.m. meeting at the Christenberry Planetarium in Samford University's Sciencenter.

The speaker, Dr. Jim Lacefield, will discuss the nature of the earth's geological record and how the planet has been affected through time by the impacts of objects such as comets, asteroids and meteorites. A semi-retired professor at the University of North Alabama, Lacefield is the author of Lost Worlds in Alabama Rocks: A Guide to the State's Ancient Life and Landscapes.
