Alan Hale, co-discoverer of Comet Hale-Bopp, will share the excitement of his discovery in a public lecture presented by the Center for Particle Astrophysics, at Lawrence Hall of Science, Wednesday, Feb. 26.

Hale-Bopp will be at its peak of visibility this spring and is expected to surpass the thrill of last year's Comet Hyakutake. Offering his special perspective about the comet and how to observe it, Hale will also discuss the formation of the solar system and current efforts to identify potential Earth-impacting objects, such as asteroids and comets.

Hale is founder and director of the Southwest Institute for Space Research in Cloudcroft, N.M., and an impassioned advocate for the advancement of scientific literacy. Following the talk, he will sign copies of his book, "Everybody's Comet: A Layman's Guide to Comet Hale-Bopp."

Hale's talk is recommended for ages 12 and up. Admission to the lecture is free. Seating is on a first-come, first-served basis.
