We present deep ground-based {it B} and {it R} observations of 12 fields in the Small Magellanic Cloud (SMC). The resulting color-magnitude diagrams (CMDs) reach the oldest main-sequence (MS) turnoff at M$_{R}$$ hicksim$3.5 and reveal the stellar population differences between the part of the galaxy facing the Large Magellanic Cloud (LMC) and an

NAHUAL is a high-resolution, near-infrared, echelle spectrograph designed for high-precision radial velocity measurements using the Gran Telescopio Canarias in La Palma. The current status of NAHUAL will be presented, as well as the prospects for the parameter space in exoplanet research that it could cover.

Physics and astronomy are the oldest sciences and the concept of mass is thus a very old concept. We have quite good understanding of the masses of composite elementary particles such as protons using quantum chromodynamics. But we do not understand the nature of the masses of the elementary particles - quarks, leptons, force carrying particles
