Laboratory for Extraterrestrial Physics
Sun-Earth Connections Seminar
(aka Brown Bag Seminar)

About the Seminar

The Laboratory for Extraterrestrial Physics (LEP) at NASA's Goddard Space Flight Center conducts weekly science seminars. They are held on Fridays at noon in the Conference Room (Room 8) in Building 2 at Goddard. The topics cover the interests of the Laboratory, including astrochemistry, interplanetary physics, planetary systems, planetary magnetospheres, and electrodynamics. Since the seminar is conducted during the lunch hour, the audience often brings their lunch, hence the moniker "brown bag seminar."
