Abstract: The Milky Way is the galaxy that contains our Solar System. It’s name “milky” is derived from it’s appearance as a dim glowing band arching across the night sky in which the naked eye cannot distinguish individual stars.
In this talk will be review the structure of the Milky Way, the galaxy where we live in, with special emphasis on open questions and present day investigation. The topics that will be touch are: galaxy formation, the spiral structure of the Milky Way, radio-astronomy and optical astronomy.

Abstract: An important unresolved question in astronomy regards the formation of massive stars (M>10Msol). These objects are located far away (>1kpc) and evolve rapidly to main sequence.
If we are to understand how young massive stars grow in mass given the presence of a strong radiation field, very high-angular resolution observations are a necessity. I will present an overview of the current state of the art of the observations and the theoretical background of massive star formation. I will shows that mass accretion activity will give rise to emission in the mid-IR wavelength range and present results from long baseline interferometry as it provides a strong potential for answering key questions in massive star formation.
The VLTI is located In the Chilean desert at Cerro Paranal and is the leading interferometry facility in the world.This school aims at training future Chilean astronomers to make use of the VLTI and other leading edge facilities.
