Studies of space plasmas have improved the understanding of phenomena in
astrophysical plasmas radically. In this context, we focus on three examples.
Magnetic seed fields of sufficient order of magnitude in the early Universe
could be explained by the same self-magnetization mechanism which has previously
discussed in context with magnetic fields in the ionosphere of Venus. Studies
regarding strongly fluctuating magnetic fields in the Earth's magnetopause
became the basis for a first self-consistent explanation of filamentary
magnetic fields in the Universe. Magnetic reconnection, well known in solar and
magnetospheric physics, was found to be a key acceleration process e.e. in
stellar or galactic jets.
