As Voyager 1 nears edge of solar system, a CU scientist looks back

CU-Boulder planetary scientist Larry Esposito talks about the Voyager missions.

Esposito is a physics professor at CU’s Laboratory for Atmospheric and Space Physics. As a member of the LASP team, Esposito helped create the photopolarimeter -- a small telescope on Voyager 1 that measures light intensity and polarization. Now the spacecraft is sending data from the edge of the solar system, which is enveloped in a giant and turbulent plasma bubble.
