Leading experts give an overview of very low frequency radio astronomy. They present for the first time in a single conference the astrophysical need for and possible instrumentation for implementing ground-based, ground-to-space, space-based, and lunar-based observations. The papers cover a wide range of topics such as solar astronomy, planetary science, supernova remnants, pulsars, interstellar thermal material, interstellar plasma refraction and diffraction, cosmic rays, extragalactic radio galaxies and quasars, ancient “fossil” radio sources, and new, coherent emission mechanisms.
