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 183) in Building 21 at Goddard. The topics cover the interests of the Laboratory, including astrochemistry, interplanetary physics, planetary systems, planetary magnetospheres, and electrodynamics.

Have an Idea for a Speaker?

The seminar organizers are always appreciative of ideas for seminar speakers. Please contact them EARLY to avoid scheduling conflicts. Contact information is located below.
