Resumen
The major breakthrough we have witnessed in physics at the
transition between XX and XXI century is a new picture of the entire Universe emerging from an impressive amount of data from observational cosmology: a flat Universe which is expanding at an accelerated rate and dominated by a large amount of a mysterious "Dark Energy" together with a
subdominant component of "Dark Matter" ( and, surprisingly enough, only a minor part of such dark matter is made of the same baryons we are made of, whilst most of it should be provided by some exotic new particles we have
never seen, not even in our high energy accelerators). These new data are fascinating and challenging not only for cosmologists, but also for particle physicists: indeed, there we find some of the very few "smoking guns" for the presence of new physics beyond the Standard Model of
particle physics. This will be the main focus of this colloquium: how "physics from the Sky" can drive us to the new particle physics, part of which we should be able to see at machines like LHC.
