Electromagnetism is present in the near-space around all the planets that have been investigated with in situ observation & measurement satellites. Plasma, electric currents, they permeate the solar system. See NASA diagram of Mercury's near-space environoment. Note: Flux Transfer Events, plasmoid, flux rope (Birkeland currents), "sputtering", plasma mantle, magnetopause current, and aurora precipitation. http://science.nasa.gov/headlines/y2009/images/mercury/mercmag.jpg NASA has broken through the "Plasma Barrier". When will the rest of "modern" astronomy do the same? Yes, indeed, electromagnetism is most evident at the surface and in the near-space around Mercury.

NASA has broken through the “Plasma Barrier”. When will the rest of “modern” astronomy do the same?

Awesome picture. Wonder what the surface temperature is? How cool is that. Awesome picture. Wonder what the surface temperature is?
