  Detailed observations of the solar system planets reveal a wide variety of
local atmospheric conditions. Astronomical observations have revealed a variety
of extrasolar planets none of which resembles any of the solar system planets
in full. Instead, the most massive amongst the extrasolar planets, the gas
giants, appear very similar to the class of (young) Brown Dwarfs which are
amongst the oldest objects in the universe. Despite of this diversity, solar
system planets, extrasolar planets and Brown Dwarfs have broadly similar global
temperatures between 300K and 2500K. In consequence, clouds of different
chemical species form in their atmospheres. While the details of these clouds
differ, the fundamental physical processes are the same. Further to this, all
these objects were observed to produce radio and X-ray emission. While both
kinds of radiation are well studied on Earth and to a lesser extent on the
solar system planets, the occurrence of emission that potentially originate
from accelerated electrons on Brown Dwarfs, extrasolar planets and
protoplanetary disks is not well understood yet. This paper offers an
interdisciplinary view on electrification processes and their feedback on their
hosting environment in meteorology, volcanology, planetology and research on
extrasolar planets and planet formation.
