The 7th International Workshop on 'Planetary, Solar and Heliospheric Radio Emissions' is the continuation of an established tradition: This PRE VII conference followed previous successful international workshops held at Graz, Austria, in 1984, 1987, 1991, 1996, 2001, and 2005. This 7th workshop in September 2010 offered again the unique opportunity to discuss the observations from Cassini at Saturn and to investigate the measurements by other spacecraft and from the ground of the Jovian, terrestrial and solar radio emissions, also including studies on radiation from exoplanetary sources.
