  The role of the SKA in high resolution observations of the formation of low
and high mass stars in the Galaxy is examined. The large collecting area will
have a large impact on dynamical studies at high resolution using spectral
lines. The SKA will allow dramatic progress in the investigation of the
ionised, atomic and molecular phases over a range of evolutionary stages.
Attention is focused here on the potential of radio recombination lines, H I 21
cm line and molecular Zeeman measurements. This combination will unveil the
physical processes that drive jets and winds from young stars. Other important
areas such as pre-biotic molecules, disc ablation in OB clusters and massive
star formation in nearby galaxies are also briefly discussed.
