NASA Holds Teleconference About Conditions At Edge Of Solar System
p.m. EDT, Thursday, June 9

NASA will host a media teleconference at 1
p.m. EDT on Thursday, June 9, to discuss a new computer model that shows the
edge of our solar system is not smooth, but filled with a turbulent sea of
magnetic bubbles.

Based on Voyager data, the finding suggests we need to
revise our picture of this previously unexplored region so critical for
understanding how cosmic rays are created and reach near-Earth space. Galactic
cosmic rays are of concern for human space travel, in particular during the
quiet periods called the solar minimum.

The teleconference panelists

– Arik Posner, Voyager program scientist, Heliophysics Division,
Science Mission Directorate, NASA Headquarters, Washington
– Merav Opher,
assistant professor, Astronomy Department, Boston University
– James F.
Drake, professor of physics, University of Maryland, College Park
– Eugene
Parker, professor emeritus, Department of Physics, University of Chicago
