Our knowledge of the Milky Way has been deeply renewed since a dozen years,
following the
results of the astrometric satellite HIPPARCOS, and those of large stellar
surveys. Many concepts
thought to be well established disappeared, to be replaced by others going
towards a larger
complexity: in particular, the discovery of radial migrations of stars has
blurred the simple image that
we had of the Galactic disk. There has been large progress in some domains,
for instance the physics
of the Galactic Center with its super-massive black hole; other problems
remain unsolved, such as
the nature of the dark matter existing like a halo around our Galaxy.
This book reviews our present knowledge of the Milky Way, in the simplest and
most didactic way
as possible. Basic notions are always recalled, which make the book accessible
to readers without
any advanced formation in astronomy. This basic work will be very helpful to
understand the
results expected from GAIA, the new ESA astrometric satellite launched on
December 19, 2013.
