in situ exploration of the Heliosphere has revealed the existence of unexpe=
cted kinds of plasmas and magnetic field configurations around the most dis=
tant planets (e.g. Uranus and Neptune) for which reliable theories can be f=
ormulated and be of help to envision the environments of a variety of recen=
tly discovered exo-planets. On larger scales, radically different kinds of =
plasmas have been found: in particular plasmas with =E2=80=9Ctemperatures i=
n the tens of keV are observed to be the main visible component of Galaxy C=
lusters, while =CE=B3-ray&nbsp;emitting plasma structures (=E2=80=9Cbubbles=
=E2=80=9D) have been seen to emerge from the disk of Our Galaxy with dimens=
ions of the same order as those characterizing the Galaxy. Although the the=
ory of the plasmas that can surround pulsars has a long history, the fact t=
hat the plasmas on the&nbsp;surface of pulsars can have inhomogeneous featu=
res (such as hot spots) and dynamics has gained attention recently. Given t=
he very high magnetic fields involved, the role of the electron thermal con=
ductivity anisotropy is shown to be an important factor in these.&nbsp;<spa=

important issues to be resolved in order to envision the plasmas that can s=
urround black holes. These involve the structures that can form, such as ri=
ngs and 3D spirals, the kind of transport of angular momentum that is neede=
d to allow plasma accretion on the black hole, etc. In fact, laboratory exp=
eriments on high-energy plasmas have cast new light on basic processes that=
 include the nature of angular momentum transport not described by a diffus=
ion equation, magnetic reconnection events and associated production of hig=
h-energy particles, self-organization processes, etc.</span></p></div><div =
